You have heard that some less-expensive tennis balls have a smaller diameter than other tennis balls so you decide to measure the average diameter in a sample of 30 Penn, 30 Wilson, and 30 Champion tennis balls. You are interested in whether the average diameter is significantly different.

What is the alternative hypothesis?

A

There is no difference in average diameter among the population of the three brands.

B

All the brands have the same average population diameter.

C

All the population mean diameters are different.

D

At least one population mean diameter is different from another.
