A) Using alpha = 0.05, determine if there is a difference in the variance of the driving distance between these two golf clubs

Solution

a) alpha = significance level = 5%

mu1 = average of Callaway and mu2 = average of nike

Comparison of two means with sample size = 10 each

Set up hypotheses as:

H0: mu1 = mu2

Ha: mu1 not equals mu2

Two tailed test.

As sample size is small, t test can be used

As p >0.7725, accept null hypothesis that the two means are equal.

There is no statistically significant difference between the two types.
