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. |
Solution
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)
