QUESTION 12 The health of employees is monitored by periodically weighing them. A sample of 74 employees has a mean weight of 185.99 lb and a standard deviation of 39.93 lb. At a significance level 5%, we want to test the claim that the population mean of all such employees weights is less than 182 lb. Calculate the test statistic of the test. If needed, round your answer to two decimal places.
