Question

You wish to test the following claim (HaHa) at a significance level of α=0.02α=0.02.

      Ho:p1=p2
      Ha:p1>p2
You obtain 35.7% successes in a sample of size n1=524n1=524 from the first population. You obtain 31% successes in a sample of size n2=671n2=671 from the second population. For this test, use the normal distribution as an approximation for the binomial distribution.

What is the critical value for this test? (Report answer accurate to three decimal places.)
critical value =

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =

The test statistic is...

• in the critical region
• not in the critical region

This test statistic leads to a decision to...

• reject the null
• accept the null
• fail to reject the null
