An important source of income for a large international banking company is home loans. The loan manager at a branch keeps track of the number of loan applicants who visit the branch's loan department per week. Over the last year, the loan manager accumulated the data shown in the table below. From previous years, the manager believes that the distribution of the number of customers has a Poisson distribution with an average of 3.6 loan applicants per week. Determine if the loan officer's belief is correct using a significance level of 0.05. Number of Customers 5 26 5 Frequencies 2 9 12 13 6 9 State the appropriate null and alternative hypotheses.

The quality control procedures aimed at maintaining the 4-inch diameter are only valid if the diameters have a normal distribution. The quality control manager recently obtained the summary diameters taken from randomly selected dowels on the production line, Is shown in the accompanying table. The dowel diameters are specified to have a normal distribution with a mean of 4 inches and a standard deviation of 0.10. Determine if the distribution of the 4-inch dowels is currently adhering to specification.

The owners of an amusement park are interested in estimating the mean spending per capita for people who visit their park. Since they do not know the population standard deviation, they plan to use the t-distribution to conduct the test. However, they realize that this requires a normally distributed population. In a random survey, 120 customers were asked the amount that they spent at the park. These data are recorded in the accompanying data table. Before estimating the population mean, the managers wish to test to determine whether the population is normally distributed. Complete parts a through d.
