A company claims that the variance of the sugar content of its yogurt is less than or equal to 25. (The sugar content is measured in milligrams per ounce.) A sample of 20 servings is selected, and the sugar content is measured. The variance of the sample is found to be 36. To test the claim, a) State the null and alternative hypothesis. b) What is the value of the test statistic?

1.A fast-food chain claims that the fat content of one of its cheeseburgers is 22 grams. A consumer health group wanted to check this claim, so it obtained a random sample of 20 cheeseburgers from the chain and measured the fat content. The fat contents (in grams) are shown below, rounded to the nearest gram. Use Excel to test whether the mean fat content is different from 22 grams. Identify the p-value from the output, rounding to three decimal places....
