Previously the average time spent on the form was 5 2 hours In order to prove that the time to prove the time to complete the form is reduced, state the approprate nul and atemative hypotheses to test Solve the problem. summary staistics In arder to conduct the test, the customer selected a significance level of.as Inberpret this value The probablity of making a Type II error is 95

Solution

1) H0: x bar = 5.2

    Ha: x bar < 5.2

Left tailed test

15) p = 0.2907

Since p value exceeds alpha there is insufficient evidence to reject null hypothesis.

3) I option.

The smallest value on that
