A marketing study conducted in a large city shows that of 100 married women who work full time, 43 at a restaurant at least one night a week during a typical workweek, while 27 out of a sample of 100 married women who do not work full time eat dinner out at least once a week. We want to know whether there is a difference between the two groups of married women in the proportion who eat dinner out at least once a week. What statistical test would be most appropriate to use? A. a t-test involving two sample proportions B. a z-test involving two sample proportions C. a t-test involving one sample proportion D. a z-test involving one sample proportion E. an F-test involving multiple means A bank is negotiating a loan on a motel which the motel owner says has an average daily revenue of at $35, 048. In the event the average is not at least $35, 048, the bank will ask the motel owner for additional collateral for the loan as protection against loan default. The loan officer has a report of the motel's daily average revenue for the past thirty days. The revenues are approximately normally distributed. What statistical test should the loan officer use to decide whether to require additional collateral for the loan? A. a r-test involving two sample means B. a z-test involving two sample means C. a t-test involving one sample mean D. a z-test involving one sample mean E. an F-test involving multiple means To examine effects of the work environment on attitude toward work, an industrial psychologist randomly assigns a group of 18 recently hired sales trainees to three room, six trainees per room. Each room is identical except for wall color. One is light green, one is light blue, and the third is deep red. During the week-long training program, the trainees stay mainly in their respective assigned rooms. At the end of the program, an attitude scale is used to measure each trainee's attitude toward work, where a low score indicates a poor attitude, a high score indicates a good attitude. The following are obtained: Based on these data, the industrial psychologist wants to determine whether there evidence that the color of the room has an effect on attitude toward work. What statistical test should be used? A. a chi-square test B. an F-test for the difference in means C. a z-test for the difference in means D. a z-test for the difference in proportions E. None of these A state transportation official claims that the mean waiting time at exit booths from a toll road near the capitol is no more than 0.40 minutes. For a sample of 35 motorists exiting the toll road, it was found that the mean waiting time was 0.46 minutes with a standard deviation of 0.16 minutes. If we want to determine whether we can reject the official's claim, what statistical test should be used? A. a t-test involving two sample means B. a z-test involving two sample means C. a t-test involving one sample mean D. a z-test involving one sample mean E. an F-test involving multiple means The personnel manager of a consumer product company asked a random sample of employees how they felt about the work they were doing. The following table gives a breakdown of their responses by gender If we wanted to know whether there was sufficient evidence to conclude that job satisfaction is not related to gender, what statistical test should be used? A. a t-test involving sample means b. an ANOVA single-factor C. an ANOVA two-factor without replication D. a chi^2 goodness-of-fit test E. a chi^2 test of independenceExplanation / Answer
Pleasse post 1 question per post. You seem to want the answer to question 38.
It is a 2 cross 3 metric wher you want to see if there is a relation between gende and response or not.
This means that the gender has relation to Response only if distribution of Response changes w.r.t to Gender
Option E. a ChiSquare test of independence is the most appropriate test to check if the two variables Response and Gender are independent of each other or not.
