Question

You wish to test the following claim (HaHa) at a significance level of α=0.10α=0.10.

      Ho:p1≥p2Ho:p1≥p2
      Ha:p1<p2Ha:p1<p2

You obtain a sample from the first population with 240 successes and 413 failures. You obtain a sample from the second population with 321 successes and 390 failures.

critical value =  
  [three decimal accuracy]
   
test statistic =  
  [three decimal accuracy]



The test statistic is...

  • in the critical region
  • not in the critical region



This test statistic leads to a decision to...

  • reject the null hypothesis
  • fail to reject the null hypothesis



As such, the final conclusion is that...

  • There is sufficient evidence to support that the first population proportion is less than the second population proportion.
  • There is not sufficient evidence to support that the first population proportion is less than the second population proportion.
