Round all final calculations to 2 decimal places.A test for the equality of population variances is first performed at a 10% level of significance.a. What is the null hypothesis ?b. What is the alternative hypotheses ?c. What is the value of the test statistic ?d. Suppose the null hypothesis stated above is rejected. Test the claim that Beta-tel installs the fibre connection quicker than Alpha tel, on average. Give the decision for the test.

Alpha-tel and Beta-tel are two companies that install fibre connections to the home. The time (in minutes) that each company takes to install their fibre connection was recorded for a random sample of clients. The data is summarized below: Alpha-tel Beta-tel (population 1) (population 2) Sample size 14 16 Average time 135 110 Standard deviation of 26 38 time
