Short Answer

A stylist realizes that the quicker she can give a permanent, the happier the customer will be. She has made a slight adjustment to her traditional routine in hopes of reducing the time required. A random sample of 13 permanents from before and 16 after were timed. The results of the tests are listed below. Assume the two samples were taken from normal populations with equal variances. Do the sample variances present sufficient evidence to indicate that the population variance before is greater than the variance after? Test the appropriate hypotheses using a significance level of 0.05. Interpret your results.
Test Statistic = ______________
Reject Region: Reject H₀ if F > ______________

There is ______________ to indicate that the population variance before is greater than the variance after.
Construct a 95% confidence interval (CI) for .
CI = ______________ Enter (n1, n2)
Find the approximate p-value for the test and interpret its value.
______________ Enter (n1, n2)
