Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet? Let $\mu$represent the population mean height of all adult American males between the ages of 18 and 21.What are the appropriate null and alternative hypotheses to answer this question? A)H₀: $\mu$ = 6 vs.H_a: $\mu$< 6 B)H₀: $\mu$= 6 vs.H_a: $\mu$ $\neq$6 C)H₀: $\mu$= 6 vs.H_a: $\mu$> 6

Quizplus · Accepted Answer

The appropriate null hypothesis is that the population mean height of adult American males between the ages of 18 and 21 is equal to 6 feet, while the alternative hypothesis is that it is greater than 6 feet. This is because we are trying to determine if the population mean height is over 6 feet, which implies a one-tailed test with the alternative hypothesis being greater than 6 feet. Therefore, choice C is the best option.
