Question

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among

2060

passenger cars in a particular region,

237

had only rear license plates. Among

374

commercial trucks,

56

had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a .05 significance level to test that hypothesis.

a. Test the claim using a hypothesis test.

b. Test the claim by constructing an appropriate confidence interval.

a. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the

passenger cars

and population 2 correspond to the

commercial trucks.

Let a success be a vehicle that only has a rear license plate.

Identify the test statistic.

(Round to two decimal places as needed.)

Identify the P-value.

(Round to three decimal places as needed.)

State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.

A.

**Fail to reject or Fail** Upper H 0H0.

There **is or is not** sufficient evidence to
support the claim that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of
passenger cars.

B.

**Fail to reject or Fail** Upper H
0H0.

There **is or is not** sufficient evidence to
support the claim that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of
passenger cars.

C.

**Fail to reject or Fail** Upper H 0H0.

There **is or is not**

sufficient evidence to support the claim that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars.Your answer is correct.

D.

**Fail to reject or Fail** Upper H 0H0.

There **is or is not** sufficient evidence to
support the claim that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of
passenger cars.

b. Identify the confidence interval limits for the appropriate confidence interval. Let population 1 correspond to the

passenger cars

and population 2 correspond to the

commercial trucks

Let a success be a vehicle that only has a rear license plate.

(Round to four decimal places as needed.)
