Land's bend sells a wide variety of outdoor equipment and clothing. The company sells both through mail order and via the internet. Random samples of sales receipts were studied for mail-order sales and internet sales, with the total purchase being recorded for each sale. A random sample of 8 sales receipts for mail-order sales results in a mean sale amount of $61.80 with a standard deviation of $17.75. A random sample of 13 sales receipts for internet sales results in a mean sale amount of $77.40 with a standard deviation of $29.75. Using this data, find the 90% confidence interval for the true mean difference between the mean amount of mail-order purchases and the mean amount of internet purchases. Assume that the population variances are not equal and that the two populations are normally distributed.
A. Find the critical value that should be used in constructing the confidence interval. B. Find the standard error of the sampling distribution to be used in constructing the confidence interval.
C. Construct the 80% confidence interval.
The assumption that the population variances are not equal and that the two populations are normally distributed is −35.713332; 0.313332.
What is a random sample?A simple random sample (or SRS) in statistics is a subset of individuals (a sample) chosen at random from a larger set (a population) with the same probability. It is the process of selecting a sample at random.To assume that the population variances are not equal and that the two populations are normally distributed:
Given:
n1 = 11 sample sizex1 = 79 for the sample means1 = 18.25 standard deviationn2 = 18 sample sizex2 = 96.70 for the sample means2 = 20.25 standard deviationSo, df = n1 + n2 - 2; 11 + 18 - 2 = 27.
T critical = T0.01, 27 = 2.473
Let,
S = sqrt[(s1²/n1) + (s2²/n2)]S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]S = 7.284Then,
(μ1 - μ2) = (x1 - x2) ± T critical × S(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284(μ1 - μ2) = - 17.7 ± 18.013332Now,
-17.7 - 18.013332 ; - 17.7 + 18.013332−35.713332 ; 0.313332Therefore, the assumption that the population variances are not equal and that the two populations are normally distributed is −35.713332; 0.313332.

Among fatal plane crashes that occurred
during the past 65 years, 260 were due to
pilot error, 62 were due to other human
error, 315
were due to weather, 682 were due to
mechanical problems, and 313 were due to
sabotage.
Fill in the relative frequency for each
category. Write answers in percentage
form and round to one decimal place as
needed. Do not include the percent
symbol.
The relative frequency are
i) Pilot error = 15.9 percent
ii) Human Error =3.8 percent
iii) Weather = 19.3 percent
iv) Mechanical problem = 42 percent
v) Sabotage = 19.2 percent
The formula for the relative frequency is = f/n
Where, f = the number of times the data occurred in an observation
n = total number of observations.
If we have to convert it into percentage form we will multiply it by 100
Thus we have been given that
Crashes due to pilot error = 260
Crashes due to other human error = 62
Crashes due to weather = 315
Crashes due to mechanical problem = 682
Crashes due to sabotage = 313
Total number of errors occurred = 260+62+315+682+313
= 1632
Hence, the relative frequency are
i) Pilot error = 260/1632 * 100 = 15.9 percent
ii) Human Error = 62/1632 * 100 =3.8 percent
iii) Weather = 315/1632 * 100 = 19.3 percent
iv) Mechanical problem = 686/1632 * 100 = 42 percent
v) Sabotage = 313/1632 * 100 = 19.2 percent

how do i do part (iii). the answer is 2 but i got the answer based on guessing. how do i do this w/o guessing? thank you.
Answer:
(i) 2² · 3 · 7
(ii) 3024
(iii) k = 16
(iv) 12 cm
Step-by-step explanation:
Part (i)The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, ...
To find which prime numbers multiply together to make 84, start by dividing 84 by the first prime number, 2:
⇒ 84 ÷ 2 = 42
As 42 is not a prime number, we need to divide again:
⇒ 42 ÷ 2 = 21
As 21 is not a prime number, we need to divide again.
21 is not divisible by 2, so let's try dividing by the next prime number, 3:
⇒ 21 ÷ 3 = 7
As 7 is a prime number, we can stop.
Therefore, 84 is the product of:
⇒ 84 = 2 · 2 · 3 · 7
As 2 appears two times, we can write this using exponents:
⇒ 84 = 2² · 3 · 7
Part (ii)Lowest Common Multiple (LCM): The lowest multiple shared by two or more numbers.
Prime Factors Method of finding LCM
Step 1
Find the prime factorization of each number.
From part (i): 84 = 2² · 3 · 7
Given in part (ii): 432 = 2⁴ · 3³
Step 2
Write each number as a product of primes, matching primes vertically where possible:
[tex]\begin{array}{ r c c c c c c c ccccccccc}84&=& 2 & \cdot & 2 & \cdot & & & & & 3& \cdot & & & && 7\\\\432 &=& 2 & \cdot & 2 &\cdot & 2& \cdot & 2& \cdot & 3& \cdot & 3& \cdot & 3\\\\\cline{1-17} \\\sf LCM & = & 2 & \cdot & 2 &\cdot & 2& \cdot & 2& \cdot & 3& \cdot & 3& \cdot & 3 &\cdot & 7\end{array}[/tex]
Step 3
Bring down the primes in each column then multiply the factors to get the LCM:
⇒ LCM = 2 · 2 · 2 · 2 · 3 · 3 · 3 · 7
⇒ LCM = 2⁴ · 3³ · 7
⇒ LCM = 3024
Part (iii)From part (ii) we know that the prime factorization of 432 is:
432 = 2⁴ · 3³
A perfect cube is a number multiplied by itself three times.
One of the factors of 432 is a perfect cube → 3³.
Therefore,
[tex]\begin{aligned}432 & = 2^4 \cdot 3^3\\\\\implies \dfrac{432}{2^4} & = 3^3\\\\\dfrac{432}{16} & = 3^3\end{aligned}[/tex]
So we need to divide 432 by 2⁴ to get the perfect cube 3³.
Therefore,
⇒ k = 2⁴
⇒ k = 2 · 2 · 2 · 2
⇒ k = 16
Part (iv)To find the largest possible length of the side of the square, we need to find the greatest common factor of 432 and 84.
Prime Factors Method of finding GCF
Step 1
Find the prime factorization of each number.
From part (i): 84 = 2² · 3 · 7
Given in part (ii): 432 = 2⁴ · 3³
Step 2
Write each number as a product of primes, matching primes vertically where possible:
[tex]\begin{array}{ r c c c c c c c ccccccccc}84&=& 2 & \cdot & 2 & \cdot & & & & & 3& \cdot & & & && 7\\\\432 &=& 2 & \cdot & 2 &\cdot & 2& \cdot & 2& \cdot & 3& \cdot & 3& \cdot & 3\\\\\cline{1-17} \\\sf GCF & = & 2 & \cdot & 2 & \cdot & & & & & 3& & & & && \end{array}[/tex]
Step 3
Bring down the primes in the columns where both numbers have the factor, then multiply the factors to get the GCF:
⇒ GCF = 2 · 2 · 3
⇒ GCF = 12
Therefore, the largest possible length of the side of the square is 12 cm.

Answer:

Step-by-step explanation:
A data set lists weights (grams) of a type of coin. those weights have a mean of g and a standard deviation of g. identify the weights that are significantly low or significantly high.
The weights that are significantly low z₁ = 5.361308 grams and significantly high z₂ = 5.48057 grams
What is Z -score?A Z-score is defined as the fractional representation of data point to the mean using standard deviations.
z -score = (z₁ - μ₀) / σ
where μ₀ is the mean and σ the standard deviation.
Consider a value to be significantly low if its z score is less than or equal to -2 or consider a value to be significantly high if its z score is greater than or equal to 2.
Here μ₀ = 5,37215 and σ = 0.05421
Substitute z -score = -2
⇒ -2 = (z₁ - 5,37215)/0.05421
⇒ (-2)(0.05421) = z₁ - 5.37215
⇒ -0.10842 = z₁ - 5.37215
⇒ z₁ = 5.37215 - 0.010842
⇒ z₁ = 5.361308
And if z = 2
Here μ₀ = 5,37215 and σ = 0.05421
Substitute z -score = 2
⇒ 2(0.05421) = z₂ - 5.37215
⇒ 0.10842 = z₂ - 5.37215
⇒z₂ = 5.37215 + 0.10842
⇒ z₂ = 5.48057
Therefore, the weights that are significantly low z₁ = 5.361308 grams and significantly high z₂ = 5.48057 grams

A bird flies from the bottom of a canyon that is 56 1/10 feet below sea level to a nest that is 822 3/10 feet above sea level. What is the difference in elevation between the bottom of the canyon and thr birds best
A bird flies from a nest that is 822 3/10 feet above sea level to the bottom of a canyon that is 56 1/10 feet below it.
The canyon is 737 feet higher than the bird's nest, by a difference of 3 feet.
based on the facts provided, we know that;
The depth below sea level is 52 3/ 5 feet, hence the value would be negative.
The height above sea level is 789 3/ 10, which requires a positive number.
Let's convert the improper fractions from the mixed fractions;
= - 263/ 5 = - 52. 6 feet
789 3/ 10 = 7893/ 10 = 789. 3 ft
the canyon's and the bird's nest's contrasting elevations;
= -52. 6 + 789. 9
Equals 737. 3 feet
Consequently, there is a 737. 3 foot difference in height between the canyon and the bird's nest.
