Q1. A. The number of orders that come into the sales office of ABC LTD each month is normally distributed with a mean of 600 and a standard deviation of 100. Approximately less than how many orders does the sales office receive such that the probability is 0.6 B. The number of orders that come into the sales office of DEF LTD each month is normally distributed with a mean of 500. Suppose the probability that the sales office receives more than 692 orders is approximately 0.1. Please calculate the standard deviation of the distribution of the orders. C. The number of orders that come into the sales office of XYZ LTD each month is normally distributed with a standard deviation of 200. Suppose the probability that the sales office receives less than 794 orders is approximately 0.15. Please calculate the mean of the distribution of the orders.
