DIRECTIONS: Round all answers to the nearest thousandth. Two new drugs are being compared for effectiveness in lowering total cholesterol levels. On the sample of 15 subjects, drug A is found to lower total cholesterol by an average of 75 mg/dl with SS = 2025. On the sample of 10 subjects, drug B lowered the mean cholesterol level by 78 mg/dl with SS = 2005. Use a 0.01 level of significance to test the claim that the two drugs are equally effective assuming populations are normally distributed. ( Use equal variance t procedure called pooled variance t procedure)

Interpret the meaning of r². Choose the correct answer below. A. It means that 2². 100% of the variation in the dependent variable can be explained by the variation in the independent variable. B. It means that (1-2). 100% of the variation in the independent variable cannot be explained by the variation in the dependent variable. C. It means that of the variation in the independent variable can be explained by the variation in the dependent variable. OD. It means that 1-2 of the variation in the dependent variable cannot be explained by the variation in the independent variable.
