O preview answers Problem 5. (1 point) Do you believe that the average age of executives from large corporations is exceedingly old? It is believed the average age of the working public is 39 with a standard deviation of 2.39, if a survey of 311 chief executive officers of large corporations finds that the sample average age to be less than 38.8 or more than 39.2, serious suspicion will be raised about the average age of executives. What is the minimum age in years (a whole number) that would make you question that the average age of CEO's is too high? Answer = What is the maximum age in years (a whole number) that would make you question that the average age of CEO's is too low? Answer = Find the absolute value of the critical values in terms of the standard normal scale, Z. Enter your answer to at least three decimal places. What level of a was used here? Enter your answer to at least three decimal places. a= If the actual average age of executives of large corporations is found to be 39.047, then what is the probability that our sample would have lead us to believe the average age of CEO's was not 39? Use at least three digits. Answer = If a sample was gathered and a 95% Confidence Interval was computed as (32.0344, 32.5656), what decision would you make based on these findings? OA.
