A hypothesis regarding the weight of newborn infants at a community hospital is that the mean is 6.6 pounds. A sample of seven infants is randomly selected and their weights at birth are recorded as 9?

To test the hypothesis that the mean weight is 6.6 pounds, you could use a one-sample t-test on the sample data. The one-sample t-test will help determine if the mean weight of the sample is significantly different from 6.6 pounds based on the data collected.
