High cholesterol diet intervention ~ Anthony is a public health nurse serving military veterans who have recently returned from combat areas. Anthony is concerned about elevated cholesterol readings among the population he serves. To help, he gathered a random sample of 11 veterans with high cholesterol. He met with each person to discuss the dangers of the condition and put them on a new diet. In the table below are the cholesterol readings of the 11 veterans both before the new diet and one month after following the diet.

Participant	Before	After	Difference = Before - After
1	243	198	45
2	250	225	25
3	207	220	-13
4	217	219	-2
5	299	224	75
6	255	245	10
7	251	215	36
8	203	196	7
9	251	237	14
10	228	196	32
11	244	230	14

Round all calculated values to 4 decimal places as appropriate.

The hypotheses should Anthony use to conduct a paired difference test to determine if the new diet decreases the mean difference in cholesterol ratings for this population is D. H0:diff=0H0:diff=0 vs. Ha:diff>0Ha:diff>0

Assume the conditions for the hypothesis test are met.

The test statistic is = 3.060

1. What is the p-value? I keep getting -.019 but it is wrong, the answer also needs to be rounded to 4 decimals.

p-value = ?

2. Construct a 95% confidence interval for the mean difference of cholesterol readings for people who are involved in this program.

The first one is correct (5.7157, ???) The second one I keep getting 38.47 but it is wrong! All need to be rounded to 4 decimals :)
