1). Archives of the Journal of Internal Medicine claimed that garlic has no effect on blood cholesterol, in other words than the mean drop in cholesterol after treating with raw garlic is 0.0 mg/dL.A clinical trial involving 64 subjects was conducted to test the effectiveness of garlic for lowering cholesterol.The sample mean for the drop in cholesterol was 5.0 mg/dL with a standard deviation of 24.0 mg/dL.

Complete the following steps using =0.02 level of significance to test whether the mean drop in cholesterol is greater than 0.0 mg/dL when treating with raw garlic.(All areas are to be reported to four decimal places; all z-scores are reported to two decimal places except the two special cases listed at the bottom of the table.)

Insert the following values from the question:

=_____ mg/dL

x =_____ mg/dL

=_____ mg/dL

n =_____subjects

=_____

Set up the hypothesis statements (no spaces between characters):

H0:__________

H1:__________

Based on the hypothesis statements, will you use or (1 - ) to solve for zcrit?__________

What area will you use to find zcrit?__________

What is the value of zcrit?__________

Use the appropriate formula to solve for ztest:__________

Is the value of ztestfurther from zero than the value of zcrit?__________

Will yourejectorfail to rejectthe null hypothesis?__________

Does the study provide evidence thatthe mean drop in cholesterol is greater than 0.0 mg/dL when treating with raw garlic?__________
