You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly less than 0.67. You use a significance level of α=0.02.

H0:p=0.67
H1:p<0.67

You obtain a sample of size n=241 in which there are 154 successes.

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) α

greater than α

This p-value 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 women over 40 who regularly have mammograms is less than 0.67.
There is not sufficient evidence to warrant rejection of the claim that the proportion of women over 40 who regularly have mammograms is less than 0.67.
The sample data support the claim that the proportion of women over 40 who regularly have mammograms is less than 0.67.
There is not sufficient sample evidence to support the claim that the proportion of women over 40 who regularly have mammograms is less than 0.67.
