Need help calculating t-statistic and P-value: Listed below are
systolic blood pressure measurements (mm Hg) taken from the right
and left arms of the same woman. Assume that the paired sample data
is a simple random sample and that the differences have a
distribution that is approximately normal. Use a 0.05 significance
level to test for a difference between the measurements from the
two arms. What can be concluded?

(PLEASE PUT HO,HA, RIGHT/LEFT TAIL, TWO TAILS,CRITICAL VALUE, ALPHA,TEST-STATISTIC,P-VALUE,DECISION AND CONCLUSION) 1. Does aspirin reduce heart attacks? In a study 11037 males physicians were given aspirin daily and 139 experience a heart attack withing a 10 year period, while 11034 male physicians were given a placebo daily and 239 experienced a heart attack in the same 10 year period. Use a significance level of .05 to test the claim that daily use of aspirin reduces the proportion of those who...

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...
