Clark Hester is an industrial engineer at Lyons Products. He would like to determine whether there are more units produced on the night shifts than on the day shift. Assume the population standard deviation for the number of units produced on the day shift is 21 and 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?
Mean threshold values and standard deviations for the three groups are given below. Normal probability plots showed the three populations were well approximated by the Normal distribution.
What is meant by illusionary correlations? Why is it so difficult for individuals to disprove their beliefs in correlations that are actually false?

For one of the first statistics exam, the coefficient of determination between hours studied and the grade earned was 80 percent. The standard error of estimate was 10.
At 5 % level of significance, does this sample prove violation of the guideline that average patient muts pay no more than $250 out-of-pocket? Is this a close decision?
A researcher has a series of Likert-scale items and a measure of frequency of absenteeism. He uses each of the Likert-scaled items in a separate bivariate correlation with absenteeism without testing for the assumptions of linear relationships. Is th..
