Question

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance

alpha

using the given sample statistics.

Claim:

pnot equals

0.22

;

alpha

equals0.05

;

Sample statistics:

ModifyingAbove p with caret

equals0.21

nequals

200

Can the normal sampling distribution be used?

No, because np is less than 5.

Yes, because both np and nq are greater than or equal to 5.

Yes, because pq is greater than

alpha

equals0.05

No, because nq is less than 5.

State the null and alternative hypotheses.

H0:

pless than or equals

0.22

Ha:

pgreater than

0.22

H0:

pequals

H0:

pgreater than or equals

0.22

Ha:

Find the z-test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

zequals

nothing

(Round to two decimal places as needed.)

The test cannot be performed.

What is the result of the test?

Reject

Upper H 0

The data do not provide sufficient evidence to support the claim.

Reject

Upper H 0

The data provide sufficient evidence to support the claim.

Fail to reject

Upper H 0

The data do not provide sufficient evidence to support the claim.

Fail to reject

Upper H 0

The data provide sufficient evidence to support the claim.

The test cannot be performed.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
