**Number of Farms:** A random sample of the number of farms (in thousands) in various states follows. Estimate the mean number of farms per state with 99% confidence. Assume \( \sigma = 31 \). Round intermediate and final answers to one decimal place. Assume the population is normally distributed.Sample data: 7, 68, 16, 48, 79, 44, 49, 3, 90, 80, 9, 57, 8, 4, 64, 33, 54, 95, 47, 50, 40, 109[Button: Send data to Excel][Box: \(\_\_\_\) < \(\mu\) < \(\_\_\_\)]

Subjects with pre‑existing cardiovascular symptoms who were receiving subitramine, an appetite suppressant, were found to be at increased risk of cardiovascular events while taking the drug. The study included 97139713overweight or obese subjects with preexisting cardiovascular disease and/ or type 22diabetes. The subjects were randomly assigned to subitramine (49974997subjects) or a placebo (47164716subjects) in a double‑blind fashion. The primary outcome measured was the occurrence of any of the following events: nonfatal myocardial infarction or stroke, resuscitation after cardiac arrest, or cardiovascular death. The primary outcome was observed in 581581subjects in the subitramine group and 474474subjects in the placebo group.Do the data give good reason to think that there is a difference between the proportions of treatment and placebo subjects who experienced the primary outcome?(a) State hypotheses, find the test statistic and use either software or the bottom row of Table A…
