Question

If μ1 and μ2 represent the mean fitness level for female teens and male teens respectively, which of the following is an appropriate pair of hypotheses in this case?

A. H0: µ1 − µ2 = 0
Ha: µ1 − µ2 < 0
B. H0: µ1 − µ2 < 0
Ha: µ1 − µ2 = 0
C. H0: µ1 = µ2
Ha: µ1 > µ2
D. H0: µ1 − µ2 = 0
Ha: µ1 - µ2 > 0

Answer 1

C

Explanation:

The null hypothesis (H0) is identified by the equality sign. This means that the population mean fitness level for both sexes is the same

The alternate hypothesis (Ha) is identified by an inequality sign. This means that the population mean fitness level for female teens is greater than that of male teens
