Question 9.2 - Sampling Distribution for the Mean Please solve the problem with simple probability rules 9. To apply for the PGA Associate Program, an applicant must pass a Playing Ability Test. Past data show the total strokesshot by applicants are normally distributed with a mean of 154.2 strokes and a standard deviation of 3.6 strokes.(c) On what interval do we find the middle 85% of stroke totals?(d) In a randomly selected group of 16 applicants, what is the probability their mean stroke total is less than 156 strokes?

Question 9.2 - Sampling Distribution for the Mean Please solve the problem with simple probability rules

9. To apply for the PGA Associate Program, an applicant must pass a Playing Ability Test. Past data show the total strokes
shot by applicants are normally distributed with a mean of 154.2 strokes and a standard deviation of 3.6 strokes.
(c) On what interval do we find the middle 85% of stroke totals?
(d) In a randomly selected group of 16 applicants, what is the probability their mean stroke total is less than 156 strokes?

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
