Ha: µ1 − µ2 = 0
C. H0: µ1 = µ2
Ha: µ1 > µ2

Answer:

C

Step-by-step 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
