Par, Inc. is a manufacturer of golf equipment and has developed a new golf ball that has been designed to provide extra distance.? In a test of driving distance using a mechanical driving device, a sample of Par golf balls was compared with a sample of golf balls made by Rap, Ltd., a competitor. We want to determine whether or not there is a significant difference between the two balls

Degree of freedom= 75

Test Statistic= -.377

Compute the two tailed Pvalue (to 3 decimals do not round). _______

Solution

Degree of freedom = 75

Test statistic t =-3.77

And this is a two tailed test.

Hence p value = 0.000323

=0.000

Conclusion: Reject null hypothesis as the two groups have the same mean.
