QUESTION 4 0*Za/2 72 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!] Continuing, using the appropriate software or spreadsheet function, determine the critical value, Za/7 rounded to the nearest thousandth? EX: #.### HINT: When computing a standard normal or score from a probability, utilize the NORM.S.INV function
