Question Help ▼ A food manufacturer claims that eating its new cereal as part of a daily diet lowers total blood cholesterol levels. The table shows the total blood cholesterol levels (in milligrams per deciliter of blood) of seven patients before eating the cereal and after one year of eating the cereal as part of their diets. Use technology to test the mean difference. Assume the samples are random and dependent, and the population is normally distributed. At a = 0.05, can you conclude that the new cereal lowers total blood cholesterol levels? Patient Total Blood Cholesterol (Before) Total Blood Cholesterol After) 1 2 3 4 215 220 235 250 260 257 255 235 205 215 240 244 253 230 Let the blood cholesterol level before eating the cereal be population 1. Let the blood cholesterol level after eating the cereal be population 2. Identify the null and alternative hypotheses, where Ha = H1 -H2. Choose the correct answer below. O A. Ho: Ha #0 O B. Ho: Ha 20 HA: Hd =0 HA: Ha <0 OC. Ho: Ha = 0 O D. Ho: Hd s0 HA: Hd >0 HA: Hd #0 Calculate the standardized test statistic. (Round to three decimal places as needed.) Calculate the P-value. P-value = (Round to four decimal places as needed.) State the conclusion.
