a. Describe the sampling distribution of Missy Walters owns a mail-order business specializing in baby clothes. Missy is confident the dollar amounts of all her orders are normally distributed or nearly so. Assume she knows the mean and standard deviation are $249 and $46, respectively, for all orders she receives. a. Describe the sampling distribution of   , where   is the mean dollar-amount of an order for a sample of 10 orders.  b. What is the probability that a simple random sample of 30 orders will provide an estimate of the population mean dollar-amount of an order that is within plus or minus $10 of the actual population mean? c. What happens to the sampling distribution of   when the sample size is increased from 30 to 90? With a sample size of 90, what is the probability that   will be between $239 and $259? , where Missy Walters owns a mail-order business specializing in baby clothes.
