You wish to test the following claim (HaHa) at a significance level of α=0.01α=0.01.

      Ho:p1=p2Ho:p1=p2
      Ha:p1>p2Ha:p1>p2

You obtain 212 successes in a sample of size 450 from the first population. You obtain 74 successes in a sample of size 226 from the second population.

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

What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =

The p-value is...

  • less than (or equal to) αα
  • greater than αα



This test statistic leads to a decision to...

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



As such, the final conclusion is that...

  • There is sufficient evidence to warrant rejection of the claim that the first population proportion is greater than the second population proportion.
  • There is not sufficient evidence to warrant rejection of the claim that the first population proportion is greater than the second population proportion.
  • The sample data support the claim that the first population proportion is greater than the second population proportion.
  • There is not sufficient sample evidence to support the claim that the first population proportion is greater than the second population proportion.
