  1. The decision rule (aka, the rejection region) for testing the following pair of hypotheses at the .01 level of significance when a sample size of 45 is taken.

H0: p = .45

Ha: p ≠ .45

  1. P (p̂ < 0.35) where p̂ is approximately normally distributed with p = .33 and n = 100.
  2. Determine the p-value for testing:

  3. H0: µ = 43

    Ha: µ ≠ 43

    when a random sample of size 30 was taken from a normal population whose standard deviation is known and the value of the test statistic equals -1.38.

  4. P (ŷ > 22) where Y has a normal distribution with a mean of 20, a standard deviation of 8, and, when a sample size of 25 was taken.
