Question

Recent attention has been given to the percentage of successful free throws that resulted in points made in men’s college basketball and the number of dribbles the shooter takes prior to the free throw. Samples of players who dribbled twice and players who dribbled four times before making free throws were randomly collected, and the number in both groups that was successful recorded:
Two Dribbles Four Dribbles
x1 = 79 ........ x2 = 112
n1 = 120 ....... n2 = 145
a. Perform a hypothesis test using α = 0.10 to determine if the proportion of successful free throws differs when players take two vs. four dribbles before shooting.
b. Determine the p value and interpret the results.
c. Construct a 90% confidence interval to estimate the difference in the proportion of successful free throws when players take two vs. four dribbles before shooting.
d. Verify your results using PHStat.
