Sony corporation conducts a study in which a sample of 44 employees is selected from one site with a population standard deviation of 3.3. The sample mean weight of the employees is 101.5kg. A sample of 46 employees is selected from a second site with a population standard deviation of 5.0kg. The sample mean weight of the employees is 99.9. Conduct the following test of hypothesis using the 0.10 significance level.

H0 : μ1 = μ2

H1 : μ1 ≠ μ2

  1. Is this a one-tailed or a two-tailed test?

  • One-tailed test

  • Two-tailed test

  1. State the decision rule. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

  1. Compute the value of the test statistic. (Round your answer to 2 decimal places.)

  1. What is your decision regarding H0?

  • Reject H0

  • Do not reject H0

  1. What is the p-value? (Round your answer to 4 decimal places.)
