Managers at an automobile manufacturing plant would like to estimate the mean completion time of an assembly line operation, u. The managers plan tochoose a random sample of completion times and estimate u via the sample. Assuming that the standard deviation of the population of completion timesis 10.4 minutes, what is the minimum sample size needed for the managers to be 90% confident that their estimate is within 2.2 minutes of u?Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimumwhole number that satisfies the requirements).(If necessary, consult a list of formulas.)

Given that Population standard deviation =10.4 Margin of error =E =2.2 90% confidence.

An IQ test is designed so that the mean is 100 and the standard deviation is 15 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 6 IQ points of the true mean. Assume that σ=15 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.
