Question

I need help with question 4, 5 and 6 

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.

4. Calculate the p-value: p-value = 5. Calculate the estimated effect size for this test: à = 6. The results of this test indicate that we have v ? evidence against the null hypothesis and a small v effect size.
