Write the null and alternative hypotheses in notation for each of the following statements.

3a. [1 point] The μ for scores on the Wechsler Adult Intelligence Test is 100.

3b. [1 point] For a population of 25- to 54-year-old women, the mean amount of television watched each day is 4.4 hours.

3c. [1 point] The mean reaction time of 19-year-old males to a simple stimulus is at least 423.0 milliseconds.

Given the following information, test whether the population mean is equal to the given value μ0. Provide the following:

  1. The appropriate test statistic (zobs or tobs)
  2. The critical value of the test statistic
  3. A statement of your conclusion (i.e., is the null rejected?)

4a. [3 points] Two-tailed test, μ0=100, σx̄=25, x̄=70, N=86, α=.01

4b. [3 points] Two-tailed test, μ0=87, Sx̄=2.9, x̄=92, N=37, α=.05
