An industrial engineer would like to determine whether there are more units produced on the night shift than on the day shift. Assume the population standard deviation for the number of units produced on the day shift is 21 and is 28 on the night shift. A sample of 54 day-shift workers showed that the mean number of units produced was 345. A sample of 60 night-shift workers showed that the mean number of units produced was 351. At the .05 significance level, is the number of units produced on the night shift larger? Note: Use day shift as first sample. The test type and the decision and the conclusion case are respectively : Select one: a.Left tail, do not reject HO , night shift larger b.Right tail, do not reject HO, night shift larger. c.Left tail, do not reject H0, night shift not larger d.Left tail, reject HO, night shift not larger e. Right tail, reject HO, night shift larger.

Suppose the mean height of women age 20 years or older in a certain country is 62.7 inches. One hundred randomly selected women in a certain city had a mean height of 63.9 inches. At the 1% significance level, do the data provide sufficient evidence to conclude that the mean height of women in the city differs from the national mean? Assume that the population standard deviation of the heights of women in the city is 3.8 inches. E Click here to view a partial table of areas under the standard normal curve. Set up the hypotheses for the one-mean z-test. Ho: H Ha:

2.Clark Heter is an industrial engineer at Lyons Products. He would like to determine whether there are more units produced on the night shift than on the day shift. The mean number of units produced by a sample of 56 day-shift workers was 338. The mean number of units produced by a sample of 62 night-shift workers was 343. Assume the population standard deviation of the number of units produced on the day shift is 24 and 31 on the night shift.Using the 0.05 significance level, is the number of units produced on the night shift larger?Required:a.

The annual commissions earned by sales representative of York Al technological machinery INC., follow the normal distribution with a mean of $128,000 and a standard deviation of $18800. The sales manager wants to award the sales representatives who earn the largest commissions a bonus of $28888. He can award a bonus to 18 percent of the sales representatives. What is the cutoff point between those who earn a bonus and those who do not?
A professor believes that, for the introductory art history classes at his university, the mean test score of students in the evening classes is lower than the mean test score of students in the morning classes. He collects data from a random sample of 150 students in evening classes and finds that they have a mean test score of 88.8. He knows the population standard deviation for the evening classes to be 8.4 points. A random sample of 250 students from morning classes results in a mean test score of 89.9. He knows the population standard deviation for the morning classes to be 5.4 points. Test his claim with a 99% level of confidence. Let students in the evening classes be Population 1 and let students in the morning classes be Population 2. Step 3 of 3 : Draw a conclusion and interpret the decision.
4. Heights of Parents. A sociologist claims that women tend to marry men who are taller than themselves? Suppose that 20 random married couples are measured. If the difference in height for each set of parents is found by subtracting the mother's height from the father's height, the mean was 4.4 inches with a standard deviation of 4.2 inches. Use a 0.01 significance level to test the claim that the mean difference is greater than 0.
