A team of health sicence students assembled a group of 40 undergrad students, 20 science majors and 20 majors in other fields, brought them to a clinic and measured their blood pressure with a hand held b/p cuff. What type of study is this, what is the most appropriate measure of assoc. to comare the systolic between the groups, what is the most appropriate statistical test. The sicence majors SBP were 100,110,116,120,122,128,128,130,132,132,134,140,144,146,146,150,152,154,158. The others were: 112, 118,120,126,130,130,130,140,142,144,144,146,150,158,160,170,170,172,190. Calculate the appropriate measure of ass., and test it statistically. What do the results mean?
