Vitamins in Milk - 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 33 skim milk bottles from a particular dairy and found the average vitamin A concentration was 606.7 micrograms per quart with a standard deviation of 13.1 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. 1. Which set of hypotheses should be used for testing this claim? ОА. Но : и %3D600 vs. Ha : и + 600 606.7 vs. Ha : u # 606.7 600 vs. Ha : и> 600 В. Но : и %— С. Но : и — D.

Each observation must be independent of the observations in the data set. E. There must be count of at least 5 quarts of milk in each category. 3.
