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 0.05 level of significance? Complete the table, then find the standard deviation of the difference s 1 3 4. First Attempt 200 235 211 219 209 Second Attempt 195 235 194 218 204 Difference d Mean d (d – d) Round all values to 3 decimal places a. The standard deviation s= b. t test statistic = C. At the 0.05 level, the critical value t. = d. Conclusion O The sample data support the original claim C There is not sufficient evidence to warrant rejection of the original claim O There is sufficient evidence to warrant the rejection of the original claim O There is not sufficient sample evidence to support the original claim
