Suppose the alternate hypothesis h1 is that mu not equal to

Solution

If H1: mu not equal to 16, then

null hypothesis H0 will be mu =16.

A common statistical method in Statistics is to compare population with sample mean. For testing whether sample mean is the same as population mean, we create hypotheses as

H0: null: mu =16 and

H1: mu not equal to 16.

Then use z test or t test depending on the sample size and come to conclusion.
