5.73 Suppose you wish to estimate a population mean correct to within .15 with a confidence level of .90. You do not know o², but you know that the observations will range in value between 31 and 39. a. Find the approximate sample size that will produce the desired accuracy of the estimate. You wish to be con- servative to ensure that the sample size will be ample for achieving the desired accuracy of the estimate. [Hint: Using your knowledge of data variation from Section 2.5, assume that the range of the observations will equal 4o.] b. Calculate the approximate sample size, making the less conservative assumption that the range of the observa- tions is equal to 60.
