We wish to test the null hypothesis: the average amount of fat content in all single servings of Vivoli's hazelnut gelati is 20 grams vs. the alternative hypothesis: the average fat content in all single servings is more than 20 grams.

The fat content in each of 9 single servings of Vivoli's hazelnut gelati is measured. On average, these servings contained 22.6 grams of fat, with SD=3.4 grams. (You may assume that the amount of fat in single servings is normally distributed.)

a) Find the value of the test statistic.

b) Find the p-value.

c) According to your answer to (b), we should accept/reject (circle one) the null hypothesis.
