Which of the following is TRUE?
| a. |
The p-value should always be larger than the selected level of significance. |
|
| b. |
If the p-value is smaller than the level of significance, then do not reject the alternate hypothesis. |
|
| c. |
If we reject the null hypothesis, it is possible that p-value is larger than the selected level of significance. |
|
| d. |
If the p-value is larger than the level of significance, then do not reject the null hypothesis. |
Homework Answers
Correct option is (d).
p-Value is the minimum value of level of significance, for which H0 can be rejected. If p-value is higher than level of significance, H0 should not be rejected.

A consumer advocate conducted a hypothesis test at the 5% significance level to determine if the mean level of impurities in a bottled water product is higher than themanufacturer’s advertised value of 20 parts per million. The advocate collected 25samples, measured the impurities, calculated a test statistic and obtained a p-value of 0.0423. Which of the following correctly states the advocate’s conclusion and reason for the conclusion? A. Reject the null hypothesis because the p-value is smaller than the significance...
