Question description

A driving examiner states that the standard deviation for times that women take to complete the written test for their driver's licenses is 2.8 minutes. In a random sample, the times that 18 women took to complete the written test had standard deviation 2.4 minutes. Use the 0.05 level of significance to test whether or not the standard deviation really is 2.8 minutes.
