To investigate this trend, the square footages of a random sample of houses built in 2008 were compared to houses built in 2018. A random sample of 45 homes built in 2008 had a sample mean of 2,449.7 square feet and a sample standard deviation of 768.5 square feet. A random sample of 50 homes built in 2018 had a sample mean of 2,227.3 square feet and a sample standard deviation of 746.9 square feet. Assume that the population variances for the square footages of houses built in these two years are equal. Complete parts a through d. a. Using a = 0.05, perform a hypothesis test to determine if the average home constructed in 2008 was larger than a home built in 2018. Identify the null and alternative hypotheses.

One way to address this question is to compare the percentage of called third strikes in the two leagues. To test this hypothesis, a random sample of plate appearances from each league was selected and the number of called third strikes was counted. The accompanying table shows the data. Complete parts a through c. Click the icon to view the third strike data. a. Perform a hypothesis test using a = 0.10 to determine if the proportion of called third strikes differs between the leagues.
