Question

You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly more than 0.38. You use a significance level of α=0.10

      H0:p=0.38
      H1:p>0.38

You obtain a sample of size n=132 in which there are 65 successes.

What is the test statistic for this sample? (Report answer accurate to four 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 proportion of men over 50 who regularly have their prostate examined is more than 0.38.
  • There is not sufficient evidence to warrant rejection of the claim that the proportion of men over 50 who regularly have their prostate examined is more than 0.38.
  • The sample data support the claim that the proportion of men over 50 who regularly have their prostate examined is more than 0.38.
  • There is not sufficient sample evidence to support the claim that the proportion of men over 50 who regularly have their prostate examined is more than 0.38.
