Statistical Averages, statistics homework help

 A cable company claims that with a new internet package, users can expect an average download speed of 16.6 Mbps. Assume a standard deviation of σ = 3.6 Mbps. You would like to know if your download speeds are different than the average, so you take a sample of 16 downloads and find an average download speed of 15.2 Mbps. Is there sufficient evidence at a α = 5% level of significance to show that your download speeds are different than 16.6 Mbps? Use the p-value to make your decision and show all 5 steps from class. Remember to check or justify whether or not the conditions are met, sketch a bell-shaped diagram showing the direction(s) of the test, and write a concluding statement.
