Suppose that in a certain hypothesis test the null hypothesis is rejected at the .10 level; it is also rejected at the 05 level: however it cannot be rejected at the ,01 level. The most accurate statement that can be made about the p-value for this test is that:

O 0.01 < p-value < 0.05. O 0.05 < p-value < 0.10. O p-value > 0.01. O p-value < 0.10.

If you don't reject the Null at Alpha = 5% then: O You will not reject at Alpha = 3%. O You will reject the Null at Alpha = 3%. O You may reject the Null at Alpha = 3%. O You will reject at Alpha = 6%

The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes. The population standard deviation is known to be 0.5 minutes. We want to test to determine whether or not the mean waiting time of all customers is significantly more than 3 minutes. The test statistic is

O 1.96 0 2.00 O 0.056 0 1.64

A random sample of 16 students selected from the Student body of a large university had an average age of 25 years. We want to determine if the average age of all the students at the university is significantly different from 24. Assume the distribution of the population of ages is normal with a standard deviation of 2 years.. At a .05 level of significance, it can be concluded that the mean age iS

O significantly less than 25 O significantly less than 24 O significantly different from 24 O not significantly different from 24
