Question 2 o*Za/2 n= E Solve the following problem in stages: According to prior research, the amount of time a medical doctor spends with patients has a standard deviation of 3.6 minutes. Further study is needed to estimate the true mean time medical doctors spend with their patients. If a researcher wants to be 96% confident that the estimate is within 1.2 minutes of the population parameter, what is the minimum sample size necessary for such findings? [COMMENTS & HINTS: Round up!] First, if the confidence level, 1 – q, is 96%, what is is complementary significance level, a, expressed as a whole percentage with percent symbol? Selected Answer: 38%
