X = size of police force in each city (thousands of police)? 

A. Autocorrelation.
B. Positive slope (due to city size).
C. High R2 (due to city size).
D. No correlation.

44) Independent events A and B would be consistent with which of the following statements: 

A. P (A) = .3, P (B) = .5, P (A B) = .4
B. P (A) = .4, P (B) = .3, P (A B) = .5
C. P (A) = .4, P (B) = .5, P (A B) = .2
D. P (A) = .5, P (B) = .4, P (A B) = .3

45) Use the following table to answer question: 


Are Service provider and county independent events? 

A. No
B. Insufficient information to determine
C. Yes

46) In a random sample of 810 women employees, it is found that 81 would prefer working for a female boss. The width of the 95% confidence interval for the proportion of women who prefer a female boss is _____.

A. A–B–C has the most slack.
B. The expected duration of this project is 25 days.
C. A–D–C is the critical path.
