PGA Golf Scores At a recent PGA tournament (the Honda Classic at Palm Beach Gardens, Florida) the following scores were posted for nine randomly selected golfers for two consecutive days. At a= .10 , is there evidence of a difference in mean scores for the two days? Assume the variables are normally or approximately normally distributed and use ud for the mean on Thursday minus the mean on Friday.

Question

PGA Golf Scores At a recent PGA tournament (the Honda Classic at Palm Beach Gardens, Florida) the following scores were posted for nine randomly selected golfers for two consecutive days. At a= .10 , is there evidence of a difference in mean scores for the two days? Assume the variables are normally or approximately normally distributed and use ud for the mean on Thursday minus the mean on Friday.

Golfer 1 2 3 4 5 6 7 8 9
Thursday 65, 68, 68, 70, 68, 70, 69, 68, 66
Friday 70, 69, 71, 70, 72, 69, 70, 75, 67

State the hypotheses and identify the claim

H0:

H1:

one tailed or two tailed

Find the critical value(s). Round the answer to at least three decimal places and ensure your degrees of freedom are correct before proceeding. If there is more than one critical value, seperate them with commas.

Critical value(s)=

Compute the test value. Round intermediate calculations and final answers to at least three decimal places

t-value:

Reject or do not reject the null hypothesis

Is there enough evidence to support the claim

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
