If our test statistic falls in the rejection region,

which of the following do we do?

If the significance level is 0.01, what is the area of each of the two tails in a two-tailed test?

Suppose our claim is

"The mean grade on the statistics test was more than 70."

What conclusion is true?

Suppose our claim is

"Twenty percent of small pizzas are too small."

What conclusion is true?

Suppose our claim is

"Small pizzas vary less than 1 inch in diameter."

If we fail to reject the null-hypothesis,

What is the correct conclusion?

Question 1

You are going to test the claim that less than 60% of women

do the income taxes for their household.

Match each of the following with its symbolic representation:

The claim.

The opposite of the claim.

The null hypothesis.

The alternative hypothesis.

Question 2

You are going to test the claim that less than 60% of women do the income

taxes for their household.

In a random sample of 600 women, 345 of them do the income taxes

for their household.

Calculate the test statistic.

Question 3

You are going to test  the claim that less than 60% of women

do the income taxes for their household.

Which kind of hypothesis test will you perform?

Question 4

You are going to test the claim that less than 60% of women

do the income taxes for their household.

If you use a significance level of 0.10,

what will the critical number be for your rejection region?

Question 5

You are going to test the claim that less than 60% of women

do the income taxes for their household.

If you use a significance level of 0.10,

and your test statistic is more than the critical number,

what will be the result of the test?

Question 6

You are going to test the claim that less than 60% of women

do the income taxes for their household.

If you use a significance level of 0.10,

which of the following should be your conclusion?
