Tme labie silows uie lulal DIOUU ChulesteloI Ieveis ( 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) 4 210 225 225 250 240 260 225 207 220 230 245 235 257 220 ...... 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 = H -H2. Choose the correct answer below. O A. Ho: Ha 20 O B. Ho: Hd = 0 HA: Ha <0 HA: Ha #0 O D. Ho: Hd#0 OC. Ho: Ha s0 HA: Ha >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. VHọ. There sufficient evidence to support the claim that the new cereal lowers total blood cholesterol levels. Fail to reject Reject

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
