TABLE 11-2. Many companies use well-known celebrities as spokespersons in their TV advertisements. A study was conducted to determine whether brand awareness of female TV viewers and the gender of the spokesperson are independent. Each in a sample of 300 female TV viewers was asked to identify a product advertised by a celebrity spokesperson. The gender of the spokesperson and whether or not the viewer could identify the product was recorded.
Referring to Table 11-2, which test would be used to properly analyze the data in this experiment?

Referring to Table 11-2, at 5% level of significance, the critical value of the test statistic is
TABLE 11-4. One criterion used to evaluate employees in the assembly section of a large factory is the number of defective pieces per 1,000 parts produced. The quality control department wants to find out whether there is a relationship between years of experience and defect rate. Since the job is repetitious, after the initial training period any improvement due to a learning effect might be offset by a loss of motivation. A defect rate is calculated for each worker in a yearly evaluation. The results for 100 workers are given in the table below.
Referring to Table 11-4, a test was conducted to determine if a relationship exists between defect rate and years of experience. Which of the following p values would indicate that defect rate and years of experience are dependent? Assume you are testing at alpha = 0.05.
TABLE 11-3. A computer used by a 24-hour banking service is supposed to randomly assign each transaction to one of 5 memory locations. A check at the end of a day's transactions gave the counts shown in the table to each of the 5 memory locations, along with the number of reported errors.

Referring to Table 11-3, which test would be used to properly analyze the data in this experiment? When using the chi-square test for independence, one should be aware that expected frequencies that are too small will lead to too big a Type I error.
