In a test of the effectiveness of garlic for lowering cholesterol, 64 subjects were treated with raw garlic. cholesterol levels were measured before and after the treatment. the changes (before minus after) in their levels of ldl cholesterol (in mg/dl) have a mean of 0.7 and a standard deviation of 1.72. use a 0.01 significance level to test the claim that with garlic treatment, the mean change in ldl cholesterol is greater than 0. what do the results suggest about the effectiveness of the garlic treatment

There is enough evidence to support the claim

Step-by-step explanation:

We are conduction a hypothesis test for dependent samples.  We want to see if there was a change in the test subjects cholesterol levels.  

For our situation:

n = 64

d = 0.7

s = 1.72

µ(d) = 0

The hypothesis are:

H0:  µ(d) = 0

Ha:  µ(d) > 0

This is a right tailed test.  

We are testing at the 1% level of significance.  Our critical region is z > 2.325

If our test statistic is in this region, we will reject the null hypothesis

See attached photo for the calculation of the test statistic and conclusion of the test

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.
