u1= $5310

u2= $2267

5310-2267= 3043

1. $3043

2. $2115, 928, 5310, 2121

3. $3043, 3247, 928, 3971

4. rejected, not rejected

5. contained, not contained

6. two tailed, left tailed, or right tailed

7. options are shown

8. 6.79, 4.5, 4.6, 9.65

9. 0.305, 0.01, <0.0001, 0.04572

10. can, or cannot

Solution

4) H0 is rejected because the value 0 is not contained in the 99% conf. interval..

5) right tailed. H0: m1-m2 =0 ag. H1: m1-m2 >0..


for the rest problems...you have to indicate standard deviation for 1st sample, 2nd sample and sample size for 1st sample and 2nd sample.....then i can show you how to do the rest parts!...
