is there any difference in the variability in golf scores for players on the lpga tour (the women's professional golf tour) and players on the pga tour (the men's professional golf tour)? a sample of tournament scores from lpga events showed a standard deviation of strokes, and a sample of tournament scores f
The difference in the variability in golf scores for players on the LPGA Tour and players on the PGA Tour can be calculated by subtracting the standard deviation for the LPGA Tour from the standard deviation for the PGA Tour.
The variability in golf scores for players on the LPGA Tour and the PGA Tour can be measured using the standard deviation. To calculate the standard deviation, the squared differences between each score and the mean score must be calculated and then averaged. Then, the square root of this average must be taken.
Formula:
Standard Deviation =√((x1–μ)2+(x2–μ)2+...+(xn–μ)2)/n
Where:
x1, x2, ..., xn are the individual observations
μ is the mean
n is the number of observations
In this case, the sample of tournament scores from LPGA events showed a standard deviation of strokes and the sample of tournament scores from the PGA Tour showed a standard deviation of strokes. The difference between the two standard deviations can then be calculated by subtracting the LPGA standard deviation from the PGA standard deviation.
Therefore, the difference in the variability in golf scores for players on the LPGA Tour and players on the PGA Tour can be calculated by subtracting the standard deviation for the LPGA Tour from the standard deviation for the PGA Tour.

y-2=3 3x - 2y =5 substitutions
Answer:
x=5
y=5
Step-by-step explanation:
y-2=3
3x-2y=5
Let's solve for y in the first equation.
y-2=3
Add 2 to both sides,
y=5
Let's substitute y=5 into the other equation.
3x-2y=5
3x-2*5=5
3x-10=5
Add 10 to both sides,
3x=15
Divide by 5 to both sides,
x=5
Therefore, x and y both equal 5.
which of the following is true of the number of hours of daylight? group of answer choices the number of hours of daylight varies depending on the latitude of the observer. the number of hours of daylight varies the least at higher latitudes. the number of hours of daylight varies the most along the equator. the number of hours of daylight includes the hours between dawn and twilight, not just the hours from sunrise to sunset.
The statement that is true about the number of hours of daylight is: "the number of hours of daylight varies depending on the latitude of the observer."
Hence, option (a) is the correct choice.
Day length will be roughly 12 hours at latitude 0° (the Equator). The Equator region has a steady 12 hour day light all year.
Day duration can be observed to extend to 24 hours or reduce to zero if latitude increases to 80° (polar circles - north or south) (depending on time of year).
The quantity of daylight received by an observer is determined by their latitude and the season.
The number of hours of daylight changes the greatest near the equator, whereas it varies the least towards higher latitudes.
The number of daylight hours covers the hours between dawn and twilight as well as the hours from sunrise to sunset.

18.3,18.4 > 18.2 Upper Control limit
14.9, > 15.4 Lower Control Limit
Step-by-step explanation:
Find the limits using μ ± 3σ and μ ± 2σ
Using μ ± 3σ
Upper Control Limit = μ + 3σ = 16.8 + 3(0.7)= 16.8 + 2.1= 18.9
Lower Control Limit = μ - 3σ =16.8 - 3(0.7)= 16.8 - 2.1= 14.7
Using μ ± 2σ
Upper Control Limit = μ + 2σ = 16.8 + 2(0.7)= 16.8 + 1.4= 18.2
Lower Control Limit = μ - 2σ =16.8 - 2(0.7)= 16.8 - 1.4= 15.4
The data points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4.

What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
here, we have,
Mathematically, we have the area of the sector as;
e/360 * pi * r^2
r is 8 cm
so we have
58 = e/360 * pi * 8^2
58/64 * 360/pi = e
e = 103.85
To get the perimeter,
we have length of the arc plus 2r
Length of the arc is;
e/360 * 2 * pi * r
add 2 r;
e/360 * 2 * pi * r + 2r
so we have
103.85/360 * 2 * pi * 8 + 2(8)

if i flip a coin and i get heads every single time, how many times do i have to flip the coin until i am 95% confident the coin is unfair?
I have to flip the coin 16 times to say that I am 95% confident the coin is unfair.
This question can be answered using the binomial distribution. If we assume the coin is fair, then each flip of the coin has a 50% chance of coming up heads. We can use the binomial distribution to calculate the probability of getting heads at least 95% of the time.
For this calculation, we need to know the number of trials, n. We can use the formula: n = (1.96^2)/(p(1-p)) to calculate n for a 95% confidence level. In this case, p = 0.5, so n = 15.84. Since this is not a whole number, we can round up to 16 flips.

b) The cost of an apricot is 43p
What is cost and how to find cost ?The cost of something depends on a variety of factors, including the quality of the product, the quantity desired, the availability of the item, the location of the purchase, and the method of payment. For example, a computer may cost more if purchased at a retail store than it would cost if purchased online. Additionally, the cost of a product can vary depending on the brand, features, and other factors. For example, a laptop may be more expensive if it has a faster processor than one with a slower processor. In general, the cost of a product or service will also depend on the demand for it, as well as the amount of competition in the marketplace. Ultimately, the cost of something is determined by the value the customer places on it.
Cost of 6 apples = £3

in a situation where the standard deviation was increased from 3.1 to 5.8, what would be the impact on the confidence interval?
The main impact of increasing the standard deviation from 3.1 to 5.8 leads to a wider confidence interval, from (9.38, 10.62) to (8.88, 11.12).
This is because the standard deviation is a measure of the spread of the data, and the wider the spread, the wider the confidence interval will be. Mathematically, this can be shown by the following calculation:
The confidence interval is usually given by the formula:
CI = x +/- (z*sigma/sqrt(n)),where x is the mean of the sample, z is the z-score representing the confidence level, sigma is the standard deviation, and n is the sample size.
In this case, let's assume that x = 10, z = 1.96 (95% confidence interval), and n = 10. Then, when the standard deviation is 3.1, the confidence interval is 10 +/- (1.96*3.1/sqrt(10)) = 10 +/- 0.62, or (9.38, 10.62).
However, when the standard deviation is increased to 5.8, the confidence interval becomes 10 +/- (1.96*5.8/sqrt(10)) = 10 +/- 1.12, or (8.88, 11.12).
Therefore, increasing the standard deviation from 3.1 to 5.8 leads to a wider confidence interval, from (9.38, 10.62) to (8.88, 11.12).
