You want to buy a box of true at a chocolate store.
(a) The time T (in minutes) you wait for service at the chocolate store is exponentially distributed. If the median waiting time is 5 minutes, what is the mean waiting time? [4]
(b) The weights W (in grams) of boxes of true at the store are normally distributed with mean 200 grams and the standard deviation is 20 grams. What is the probability that the box of true you buy weighs more than 221 grams?

The time to process orders at the service counter of a pharmacy store are exponentially distributed with mean 5 minutes. Suppose that 100 customers visit the counter in a day. Use CLT to estimate the following. (1) What is the probability that the total service time of the 100 customers does not exceed 10 hours? (2) What is the probability that at least half of the 100 customers need to wait more than 3.47 minutes? (Note: to simply the calculations,...

Use the standard normal distribution or the t-distribution to construct the indicated confidence interval for the population mean of each data set. Justify your decision. If neither distribution can be used, explain why. Interpret the results. (a) In a random sample of 36 patients, the mean waiting time at a dentist’s office was 24 minutes and the standard deviation was 7.5 minutes. Construct a 90% confidence interval for the population mean. (b) In a random sample of 25 cereal boxes,...
