Milk is a good source of many vitamins that can help us stay healthy. Regulatory agencies in the US suggest that skim milk should be fortified with Vitamin A at the level of 600 micrograms per quart.A study in 2016 collected a sample of 36 skim milk bottles from a particular dairy and found the average vitamin A concentration was 604 micrograms per quart with a standard deviation of 14.2 micrograms per quart.A medical researcher wants to determine if the mean vitamin A concentration in skim milk from this dairy is different from 600 micrograms per quart.
