An important feature of modern tablets is battery life. Here, we wish to compare how tow popular tablets brands perform in this area. You collect a sample of 16 Ipad tablets and 13 Surface tablets. The ipad sample had a mean of 600 minutes of battery life, with a standard deviation of 6.88 minutes. Meanwhile, the Surface sample had a mean of 625 minutes and a standard deviation of 6.03 minutes. We wish to know if the Ipad tablets have a higher variance in battery life than the Surface tablets. Battery life has a normal distribution in both populations, and you are asked to use α = 0.05

Expert Solution
As we fail to reject H0 at 5% los, we conclude that the claim is false that the the ipad tablet having higher variance than the surface tablets.

We wish to compare three interventions for preterm infants, with
regard to effects on the infants’ heart rates: Nonnutritive Sucking
(NNS), Nonnutritive Sucking plus Rocking (NNSR), and Rocking (R).
Nine infants are randomly assigned to six different orderings of
the three treatments. Heart rate, the dependent variable, is
measured after each treatment. The data are summarized in the
following table.
