You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 0.49. You use a significance level of α=0.002α0.002.

H0:p=0.49H0p0.49
H1:p≠0.49H1p0.49

You obtain a sample of size n=318n318 in which there are 182 successes.

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 proportion of women over 40 who regularly have mammograms is different from 0.49.
• There is not sufficient evidence to warrant rejection of the claim that the proportion of women over 40 who regularly have mammograms is different from 0.49.
• The sample data support the claim that the proportion of women over 40 who regularly have mammograms is different from 0.49.
• There is not sufficient sample evidence to support the claim that the proportion of women over 40 who regularly have mammograms is different from 0.49.
