Question
1. For each claim below, write: (1) claim in mathematical form; (2) Null
hypothesis (Ho); (3) alternative hypothesis (Hp); (4) what tailed test. Use notations
MuMz (for mean), PuP2 (for proportion), 01,02 (for standard deviation), Mo (for
differences in means for dependenr (i.e., matched pair) samples)
(a) Claim: California HS students on an average score lower in the SAT than
Massachusetts HS students (1 = California, 2 = Massachuselts)
(b) Claim: The proportion of smokers in Texas is the same as that in Oklahoma
(1 = Texas, 2 = Oklahoma)
(c) Claim: The standard deviation of weights in 8 oz Coke cans is at least as
high as that in Pepsi cans (1 - Coke, 2 - Pepsi)
(d) Claim: Ethiopian track athletes are, on an average, faster long-distance
runners than the USA track athletes (1 - Ethiopia, 2 - USA)
(e) Claim: The cholesterol level before taking Lipitor is, on an average, higher
than that after taking the drug (I - Before drug, 2 - Aller drug)
