Chapter 8.1, Problem 2E

For the following pairs of assertions, indicate which do not comply with our rules for setting up hypotheses and why (the subscripts 1 and 2 differentiate between quantities for two different populations or samples):

  1. a. H0: μ = 100, Ha: μ > 100
  2. b. H0: σ = 20, Ha: σ ≤ 20
  3. c. H0: p ≠ .25, Ha: p = .25
  4. d. H0: μ1μ2 = 25, Ha: μ1μ2 > 100
  5. e. H 0 : S 1 2 = S 2 2 , H a : S 1 2 S 2 2
  6. f. H0: μ = 120, Ha: μ = 150
  7. g. H0: σ1/σ2 = 1, Ha: σ1/σ2 ≠ 1
  8. h. H0: p1p2 = −.1, Ha: p1p2 < −.1

Which pair of hypotheses would be correct for the following claim: Claim: The average human body temperature is 98.6◦ F. A. H0 :μ=98.6and H1 :μ<98.6 B. H0 :μ<98.6andH1 :μ=98.6 C. H0 :μ=98.6andH1 :μ̸=98.6 D. H0 :μ̸=98.6andH1 :μ=98.6 E. H0 :μ=98.6andH1 :μ>98.6 F. H0 :μ>98.6andH1 :μ=98.6
Express the null and alternative hypotheses in symbolic form for this claim: the mean weight of male nurses working at a local hospital is less than 187 lbs. Note that the mean weight in the sample taken is 197 lbs. H1:H
1. For this study, we should use a. t-test for a population mean b. z-test for a population proportion  2. The null and alternative hypotheses would be:   H0: p or μ a. < b. > c. = d. ≠ H1: p or μ a. < b. > c. = d. ≠ 3. z or t
