Question

1. Active management of labor (AML) is a group of interventions designed to help reduce the length of labor and the rate of cesarean deliveries. Physicians from the Department of Obstetrics and Gynecology at the University of New Mexico Health Sciences Center were interested in determining whether AML would also translate into reduced cost of delivery. According to their study, 500 AML deliveries had a sample mean cost of $2,480 dollars with a sample standard deviation of $766.

The average cost of all AML deliveries is to be estimated with 90% confidence interval.

The ? − or ? −value that should be used to construct this interval is
1. 1.96
2. 2.33
3. 1.645
4. 1.28
The margin of error is equal to
1. 67.14
2. 79.82
3. 43.85
4. 56.35
The confidence interval is
1. (2423.65, 2536.35)
2. (2421.86, 2547.14)
3. (2409.18, 2559.82)
4. (2445.15, 2523.85)
