A community health association is interested in estimating the
average number of maternity days women stay in the local hospital.
A random sample is taken of 36 women who had babies in the hospital
during the past year. The following numbers of maternity days each
woman was in the hospital are rounded to the nearest day.
4 | 3 | 4 | 3 | 2 | 5 | 3 | 1 | 4 | 3 |
4 | 2 | 3 | 5 | 3 | 2 | 4 | 3 | 2 | 4 |
1 | 6 | 3 | 4 | 3 | 3 | 5 | 2 | 3 | 4 |
3 | 5 | 4 | 3 | 5 | 1 |
Use these data and a population standard deviation of 1.11 to
construct a 98% confidence interval to estimate the average
maternity stay in the hospital for all women who have babies in
this hospital.
(Round the intermediate values to 3 decimal places.
