A student believes the average age (in years) of persons killed by police (between 2000 and 2020) is 41. The student wants to test this idea. Another researcher has already found a 99.9% confidence interval for this average age: namely, [29.7,39.5]. The student decides to hypothesis test using this confidence interval. Clearly state the null hypothesis and the alternative hypothesis. Then decide whether the student should reject the null hypothesis, explaining clearly how you decided. Finally state the student's conclusion from the study
