Suppose a large labor union wishes to estimate the mean number of hours per month a union member is absent from work. the union decides to sample 348 of its members at random and monitor the working time of each of them for 1 month. at the end of the month, the total number of hours absent from work is recorded for each employee. if the mean and standard deviation of the sample are x = 7.5 hours and s = 3.5 hours, find a 99% confidence interval for the true mean number of hours a union member is absent per month. round to the nearest thousandth.

Ответ:
y=x
Step-by-step explanation:
When the pentagon is reflected across y=x, all of its points are placed equally distant from the diagonal on one side as they are from the other. This causes the figure to turn 90 degrees instead of flipping like in any of the other reflections. Hope this helps!
