Question 2 Scientists believe that global warming has changed the mean temperature. To measure this effect is construct a 90% confidence interval for the sample mean. The sample standard deviation of the minimum temperature in the Salt Lake area is 2.47, and the sample mean is 42.35 on 36 degrees of freedom. The mean temperature of the daily minimum in SLC was 39.22 before 1980. If this mean value is not contained in the confidence interval we reject the null hypothesis. See: https://www.nytimes.com/2019/02/28/learning/teach-about-climate-change-with-these-24- new-york-times-graphs.html e Note this is real data obtained from the weather stations in SLC.
