Discuss the below:
The duration of human gestation is on average 40.5 weeks. In a maternity ward, we note the gestational age of 100 consecutive newborns. The sum of these ages is equal to 3850 weeks and the standard deviation is 5 weeks. We believe that it is a ward for premature births. Do we have enough evidence to support our claim? Make sure you specify the test statistic that you are using and properly formulate Ho (Null Hypothesis) and Ha (Alternate Hypothesis).
