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.
