1)You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 0.7. You use a significance level of

=0.005

H0:p=0.7

H1:p0.7

You obtain a sample of sizen=219 in which there are 166 successes.

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

p-value =____________

2)You wish to test the following claim (Ha) at a significance level of=0.002.

Ho:p=0.39

Ha:p<0.39

You obtain a sample of sizen=153in which there are 49 successful observations.

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

p-value =_________________

3) Test the claim that the proportion of people who own cats is smaller than 60% at the 0.01 significance level.

The null and alternative hypothesis would be:

H0:p=0.6

H1:p<0.6

Based on a sample of 600 people, 58% owned cats

The p-value is:_____________(to 2 decimals).

4)You wish to test the following claim a significance level of=0.005.

H0:p = 0.21

Ha:p 0.21

You obtain a sample of size n= 463 in which there are 75 successful observations.

a)What is the test statistic for this sample? The test statistic can be found in the calculator's results for the test. The test statistic is labeled as z= just above the p= in the calculator's results window for the Z-Test.

test statistic =______________Round to 3 decimal places.

b)What is the p-value for this sample?

P-value =____________Round to 4 decimal places.
