Suppose Company Beze wants to determine the mean age of CEOs in the United States of America. Beze wants to be 97% confident of the average age from the sample within one and eight tenths years. If the range of CEOs ages is known to 25 to 61. a) What is the estimate of the population of standard deviation? (Round to four decimal places) b) What is the Z score for a 97% confidence level? (Round to two decimal places) c) What is the error bound or margin of error? (Round to two decimal places) d) What is the sample size Beze should take? (Round up to next Integer. However, if the answer is an integer enter the integer.)
