In computing the standard error of the mean, the finite population correction factor is not used
when:
a. n ≥ 30
b. n/N ≤ 0.05
c. N/n ≤ 0.05
d. n/N > 0.05 - ANSWER-b. n/N ≤ 0.05
QUESTION: Which of the following is(are) point estimator(s)?
a. σ
b. μ
c. s

QUESTION: A population has a mean of 180 and a standard deviation of 24. A sample of 64
observations will be taken. The probability that the mean from that sample will be between 183
and 186 is
a. 0.8185
b. 0.1359
c. 0.4772
d. 0.3413 - ANSWER-b. 0.1359
1. st. error: 24/sqrt(64) = 3
2. z value (upper): (186-180)/3 = 2
3. Norm.s.dist(1, true) = .9772
4. z value (lower): (183-180)/3= 1
5.Norm.s.dist(-1,true)= .8413
6. 0.9772-.8413=0.1359
QUESTION: The basis for using a normal probability distribution to approximate the sampling
distribution of xbar and pbar is:
a. the empirical rule
