B. decreasing the sample size
C. none of the these affect sampling error
D. increasing the sample size **Weegy:** Sampling error can be reduced by increasing the sample size. **User:** 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. ± .0105
B. ± .0196
C. ± .0288
D. ± .0207
**Weegy:** B. ??? .0288 **User:** Which of the following statements is true?
A. The sum of two mutually exclusive events is one.
B. The probability of A and its complement (A') will always sum to one.
C. If A and B are independent events, the P(B) = P(A) P(B).
D. If event (A) occurs, then its complement (A') will also occur.
**Weegy:** B. The probability of A and its complement (A') will always sum to one is the true statement **User:** ) Independent events A and B would be consistent with which of the following statements:
A. P (A) = .4, P (B) = .3, P (A B) = .5
B. P (A) = .3, P (B) = .5, P (A B) = .4
C. P (A) = .5, P (B) = .4, P (A B) = .3
D. P (A) = .4, P (B) = .5, P (A B) = .2 **Weegy:** The answer is D. [ P (A) = .4, P (B) = .5, P (A B) = .2.
Multiplication Rule for Independent events A and B : When two events, A and B, are independent, the probability of both occurring is:
P(A and B) = P(A) · P(B)
