Question
A drug manufacturer claims that a new drug lowers cholesterol level in patient studied. The following data shows the levels of cholesterol in 5 patients before and after taking the drug. Assume the data is normally distributed. Is there enough evidence to support the claim at a 0.02 level of significance? Complete the table, then find the standard deviation of the difference sa 3 4. First Attempt 224 235 219 224 215 Second Attempt 227 229 207 218 200 Difference d Mean d (d – d) Round all values to 3 decimal places a. The standard deviation sa = b. t test statistic = C. At the 0.02 level, the critical value t = d. Conclusion O There is not sufficient sample evidence to support the original claim O There is not sufficient evidence to warrant rejection of the original claim O The sample data support the original claim O There is sufficient evidence to warrant the rejection of the original claim
