Question

You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly less than 0.69. You use a significance level of ? = 0.10. H0: p = 0.69 H1: p < 0.69 You obtain a sample of size n = 427 in which there are 263 successes. What is the test statistic for this sample? (Use GeoGebra. Report answer accurate to three decimal places.) Test statistic: What is the p-value for this sample? (Use GeoGebra. Report answer accurate to four decimal places.) p-value: The p-value is less than (or equal to) ?. This test statistic leads to a decision 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 0.69.

H0: p = 0.69
H1: p < 0.69

You obtain a sample of size n = 427 in which there are 263 successes.

What is the test statistic for this sample? (Use GeoGebra. Report answer accurate to three decimal places.)
Test statistic: 

What is the p-value for this sample? (Use GeoGebra. Report answer accurate to four decimal places.)
p-value: 

The p-value is less than (or equal to) ?.

This test statistic leads to a decision 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 0.69.
