Question

Researchers determined that 60 Kleenex tissues is the average number of tissues used during a cold. Suppose in a random sample of 100 Kleenex users, the average number of tissues used during cold was 52 with a standard deviation of 22.    Suppose the test statistic does not fall in the rejection region at = 0.05. Which of the following conclusions is correct?

At = 0.05, we reject H0.

At = 0.05, we accept H0.

At = 0.05, we do not reject H0.

Both a and c.

At = 0.05, we reject H0.

At = 0.05, we accept H0.

At = 0.05, we do not reject H0.

Both a and c.

Explanation / Answer

Suppose the test statistic does not fall in the rejection region at = 0.05. Which of the following conclusions is correct?

the correct is B and C at alpha = 0.05 we accept Ho that is the same that I say we do not reject Ho

because if t test statisitc not fall in rejection region that means that we accept Ho ( we dont reject Ho)
