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)

What can the chi-square test do that none of the other tests we learned this semester could do?     analyze homogeneous data     nalyze normal data     analyze parametric data     analyze frequency data

In a study to investigate the extent to which individuals are aware of industrial odors in a certain regiont, a sample of individuals was obtained from each of three different areas near industrial facilities. Each individual was asked whether he or she noticed odors (1) every day, (2) at least once/week, (3) at least once/month, (4) less often than once/month, or (5) not at all, resulting in the data and SPSS output below.
