A diet guide claims that you will consume 120 calories from a serving of vanilla yogurt. A random
sample of 22 brands of vanilla yogurt produced a mean of 118.3 calories with standard deviation 3.7
calories.
Suppose that mu is the true mean number of calories for a serving of vanilla yogurt. We want to test if
the diet guide’s claim is accurate. Use significance level 0.05.
1. What are the null and alternative hypotheses?
2. What is the value of the test statistic?
3. What is the rejection region?
4. Do we reject the null hypothesis?
5. Based on this hypothesis test, do we conclude the diet guide is accurate or inaccurate?
6. Should the p-value for this test be greater than or less than the significance level?
