The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.8 and a standard deviation of 1.72 Use a 0.05 significance evel to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than O. What do the results sugpest about the offectiveness of the garlic random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-vaiue, and state the final conclusion that addresses the original claim. What are the null and altemative Determine the test statistic. (Hound to two decimal places as needed.) Determine the P-value (Round to three decimal places as needed.) evidence to conclude that the mean of the popuiation of changes

Explanation / Answer

Ho :- mu = 0

Ha :- mu > 0

This one tailed t test

t score = 2.79

The P-Value is 0.004.

Pvalue = 0.004 < 0.05 = level of significance

The result is significant at p < 0.05.

We reject null hypothesis

Reject Ho there is enough evidence to claim that mean of population of changes greater than 0
