The ages of randomly selected passenger cars and taxis were recorded by textbook author Mario Triola when he visited Dublin. Use a 0.05 significance level to test the claim that both personal cars and taxis in Dublin have the same variation in ages.

Car Ages: 4, 0, 8, 11, 14, 3, 4, 4, 3, 5, 8, 3, 3, 7, 4, 6, 6, 1, 8, 2, 15, 11, 4, 1, 6, 1, 8

Taxi Ages: 8, 8, 0, 3, 8, 4, 3, 3, 6, 11, 7, 7, 6, 9, 5, 10, 8, 4, 3, 4

Group of answer choices

A. F = 1.8714, We fail to reject the claim

B. F = 1.8714, We reject the claim

C. F = 2.3937, we fail to reject the claim

D. F = 2.3937, we reject the claim

Expert Solution

From the given information

Using Ti 83

Test statistic,

F=1.88 approximately equal to

F=1.8714

P-value =0.1615

Alpha = 0.05

P-value > alpha

Fail to reject null hypothesis.

When the author visited Dublin, Ireland, he recorded the ages of randomly selected passenger cars and randomly selected taxis. The ages can be found from the license plates. The ages in years are listed below. We might expect that taxis would be newer, so test the claim that the mean age of cars is greater than the mean age of taxies. Car Ages: 4 0 8 11 4 14 3 3 7 6 6 6 15 9 Taxi Ages: 8...

Students at a college randomly selected 217 student cars and found that they had ages with a mean of 7.89 years and a standard deviation of 3.67 years. They also randomly selected 152 faculty cars and found that they had ages with a mean of 5399 years and a standard deviation of 3.65 years. a) Using a 0.05 significance level, are student cars older than faculty cars? List: Define the parameters u1 and u2 Null and Alternative Hypothesis P-value Initial...

A sample of 21 randomly selected student cars have ages with a mean of 7.5 years and a standard deviation of 3.4 years, while a sample of 32 randomly selected faculty cars have ages with a mean of 5.5 years and a standard deviation of 2.8 years. First, define student cars as Population 1 and faculty cars as Population 2. Thus we have n1=21, n2=32, x¯1=7.5, x¯2=5.5, s1=3.4, s2=2.8, (a) Based on the study data, is there significant evidence that...
