Question

PGA Golf Scores At a recent PGA tournament (the Honda Classic at Palm Beach Gardens, Florida) the following scores were posted for eleven randomly selected golfers for two consecutive days. At

α=0.20, is there evidence of a difference in mean scores for the two days? Assume the variables are normally or approximately normally distributed and use μD for the mean on Thursday minus the mean on Friday.

Golfer 1 2 3 4 5 6 7 8 9 10 11

Thursday 69 70 68 70 68 68 65 67 65 64 66

Friday 75 67 74 70 67 68 70 69 71 72 69

(a) State the hypotheses.

H0: claim/do not claim?

H1: claim/do not claim?

This hypothesis test is one tailed/two tailed?

(b) Find the critical value. Enter the answers in ascending order and rounded to at least three decimal places.

Compute the test value. Round score values to at least three decimals places.

Make the decision.

Reject/Do not reject the null hypothesis

(e) Summarize the results.

There ▼(Choose one) sufficient evidence to support the claim that there is a difference in the mean scores for the two days.

Critical values are

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 + ...
