The following hypotheses are given.

H0: π = 0.40
H1: π ≠ 0.40

A sample of 120 observations revealed that p = 0.30. At the 0.05 significance level, can the null hypothesis be rejected?

  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. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.)

  1. What is your decision regarding the null hypothesis?

  • Do not reject H0

  • Reject H0
