In an article in the Jouroai of Management, Joseph Martocchio studied and estimated the costs of employee absences. Based on a sample of 13"6 bluecollar workers, Martocchio estimated that the mean amount of ,oaio'time lost during a threemonth period was 1.3 days per employee with a standard deviation of 1.1 days- Martocchio also estimated that the mean amount of unpaid time lost during a threemonth period was 1.2 day per employee with a standard deviation of 1.8 days. Suppose we randomly select a sample of 1iCIiI|ZiI bluecollar workers. Based on Martocchio's estimates: [a] What is the probability that the average amount of paidtime lost during a threemonth period for the 1GB bluecollar workers will exceed 1.5 days? [Use the rounded mean and standard error to compute the rounded Z-score used to nd the probability. Round means to 1 decimal place, standard deviations to 2 decimal places, and probabilities to 4 decimal places. Round z-value to 2 decimal places.} lb} What is the probability that the average amount of unpaidtime lost during a threemonth period for the 100 bluecollar workers will exceed 1.5 days? [Use the rounded mean and standard error to compute the rounded Z-score used to nd the probability. Round standard deviations to 2 decimal places and probabilities to 4 decimal places. Round z-value to 2 decimal places.) (c) Suppose we randomly select a sample of 100 blue-collar workers, and suppose the sample mean amount of unpaid time lost during a three-month period actually exceeds 1.5 days. Would it be reasonable to conclude that the mean amount of unpaid time lost has increased above the previously estimated 1.2 days? the probability of observing the sample is if the mean is actually 1.2
