To investigatethis trend, the square footages of a random sample of houses built in2008 were compared to houses built in 2018. A random sample of 45homes built in 2008 had a sample mean of 2,462.3 square feet and asample standard deviation of 760.8 square feet. A random sample of40 homes built in 2018 had a sámple mean of 2,257.0 square feet anda sample standard deviation of 730.2 square feet. Assume that thepopulation variances for the square footages of houses built in thesetwo years are equal. Using a = 0.05, perform a hypothesis test todetermine if the average home constructed in 2010 was larger than ahome built in 2018 and construct a 95% confidence interval to estimate10.the average difference in the square footages of new homesconstructed in these two years.

2 part question done in Excel. 1. Data are collected in a clinical trial evaluating a new compound designed to improve wound healing in trauma patients. The new compound is compared against a placebo. After treatment for 5 days with the new compound or placebo, the extent of the wound healing is measured and the date are show in the table below. Is there a difference in the extent of wound healing by treatment (Hint: Are treatment and the percent wound healing independent?) Run the appropriate tes at a 5% level of significance. 2. Use the data in Problem 1 and pool the data across the treatments into one sample of size n=250. Use the pooled data to test whether the distribution of the percent wound healing is approximately normal. Specifically, use the following distributions: 30%, 40%, 20%, and 10%. Run the appropriate test at a = 0.05.
