1/1 POINTS
A fitness center claims that the mean amount of time that a person spends at the gym
per visit is 33 minutes. Identify the null hypothesis, H0, and the alternative
hypothesis, Ha, in terms of the parameter μ.
That is correct!
H0: μ≠33; Ha: μ=33
H0: μ=33; Ha: μ≠33
H0: μ≥33; Ha: μ<33
H0: μ≤33; Ha: μ>33
Answer Explanation
Correct answer:
Let the parameter μ be used to represent the mean. The null hypothesis is always
stated with some form of equality: equal (=), greater than or equal to (≥), or less than or
equal to (≤). Therefore, in this case, the null hypothesis H0 is μ=33. The alternative
hypothesis is contradictory to the null hypothesis, so Ha is μ≠33.

H0:X≥17.1, Ha:X<17.1
H0:X=14.4, Ha:X≠14.4
H0:X≤3.8, Ha:X>3.8
H0:X≤7.4, Ha:X>7.4
H0:X=3.3, Ha:X≠3.3
ï‚·
Answer Explanation
Correct answer:
Remember the forms of the hypothesis tests.
ï‚· Right-tailed: H0:X≤X0, Ha:X>X0.
ï‚· Left-tailed: H0:X≥X0, Ha:Xï‚· Two-tailed: H0:X=X0, Ha:X≠X0.
So in this case, the right-tailed tests are:
ï‚· H0:X≤7.4, Ha:X>7.4
