Suppose that the average distance PGA tour players can drive a golf ball off the tee is 295.3 yards with a standard deviation of 15.15 yards. Suppose a randomly collected sample of 10 PGA tour players returned an average driving distance of 295.44 yards. Does this sample provide evidence that PGA tour players have an average driving distance that exceeds 295.3 yards at the 5% significance level? Assume that driving distance is normally distributed.

Question

Suppose that the average distance PGA tour players can drive a golf ball off the tee is 295.3 yards with a standard deviation of 15.15 yards. Suppose a randomly collected sample of 10 PGA tour players returned an average driving distance of 295.44 yards. Does this sample provide evidence that PGA tour players have an average driving distance that exceeds 295.3 yards at the 5% significance level? Assume that driving distance is normally distributed.

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.
