1. Conduct a two-sample t-test at a 1% level of significance to find out if the U.S. stock returns significantly outperform the U.S. corporate bond returns using the monthly data covering the sample period 1980-2019. Please explain the hypothesis and how to use the summary to answer the question.
7. With a previous contractor, the mean time to replace a streetlight was 3.2 days. A city councilwoman thinks that the new contractor is not getting the streetlights replaced as quickly. She selects a random sample of 12 streetlight service calls for the new contractor, and obtains the following times to replacement (days). 6.2 7.1 5.4 5.5 7.5 2.6 4.3 2.9 3.7 0.7 5.6 1.7 Using a significance level of 0.01, test the councilwoman's claim. You may assume that all conditions are satisfied.
