B2. In this exercise, run the exact same analysis as in Exercise B1, except select the option Exclude cases listwise as the Missing Values option. Then answer the following questions:

(a) How many cases were in this analysis? Why do you think so few women were included in this analysis—

for example, why wasn’t the N 425, which corresponds to the number of women who had a nonmissing value for workweek?

(b) Comment on some of the differences in the descriptive statistics for this subsample of women and the more complete sample for Exercise B1.

(c) How many correlations were significant in this exercise? Was the number of significant correlations smaller or larger than in Exercise B1? Why do you think there is a difference?

(d) What is the strongest correlation in this matrix? How much variance is shared between the two variables in question?
