Claim: Less than 70% of phone numbers in a certain city are unlisted.

Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage).

H0:p

H1:p

The mean weight of male aerobics instructors in a certain city is more than 182 lbs. Express the null and alternative hypotheses in symbolic form for this claim.

H0:

H1:

If your claim is in the alternative hypothesis and you reject the null hypothesis, then your conclusion would be:

1. There is not sufficient sample evidence to support the original claim
2. There is not sufficient evidence to warrant rejection of the original claim
3. The sample data support the original claim
4. There is sufficient evidence to warrant rejection of the original claim

You are performing a right-tailed z-test

If=.005, and your test statistic isz=2.19, do you:

1. Reject Null Hypothesis
2. Fail to Reject Null Hypothesis

If your null and alternative hypothesis are:

H0:p1=p2

H1:p1

Then the test is:

1. left tailed
2. right tailed
3. two tailed

_________________________________________________________________________

your null and alternative hypothesis are:

H0:=17

H1:<17

Then the test is:

1. right tailed
2. two tailed
3. left tailed

_________________________________________________________________________

If your null and alternative hypothesis are:

H0:p=0.62

H1:p>0.62

Then the test is:

1. left tailed
2. right tailed
3. two tailed

You are performing a right-tailed t-test with a sample size of 29.

=.05, and your test statistic ist=1.67, do you:

1. fail to reject the null hypothesis
2. reject the null hypothesis

You will either want to either:

• Calculate the critical value and compare the test statistic to it.
• Calculate the p-value and compare it to the significance.

You are performing a right-tailed t-test with a sample size of 13.

=.025, and your test statistic ist=3.02, do you:

fail to reject the null hypothesis

reject the null hypothesis

You will either want to either:

• Calculate the critical value and compare the test statistic to it.
• Calculate the p-value and compare it to the significance.

_________________________________________________________________________

You are performing a right-tailed t-test with a sample size of 23.

=.1, and your test statistic ist=2.07, do you:

1. fail to reject the null hypothesis
2. reject the null hypothesis

You will either want to either:

• Calculate the critical value and compare the test statistic to it.
• Calculate the p-value and compare it to the significance.
