Question

A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach.

Sample mean = 7.5                 s = 1.8             n = 18              α = 0.01

H0: µ = 10

H1: µ <10

  1. The test statistics is  (Round to three decimal places)
  2. The critical value(s) is/are  (If there are two critical values separate each with a comma.)
  3. The decision is to  the null hypothesis. (Enter R if you reject and enter F if you fail to reject)
