Ages of Dogs The average age of pet dogs is 4.3 years. Two random samples of pet owners who own dogs are selected. Sample 1 of 13  dog owners was selected from owners who live in Miami. The standard deviation of the ages of the dogs in this sample is 1.1 years. Sample 2 of 10 dog owners was selected from dog owners who live in Boston. The standard deviation of these dogs was 0.5 year. At α=0.01, can it be concluded that there is a difference in the variances? Use the critical value method and tables.

 

(a)State the hypotheses and identify the claim.
 
 
 
 
 

 

:H0  ▼(Choose one)

:H1 ▼(Choose one)

This hypothesis test is a ▼(Choose one) test.
 
 
 
 
 
 
(b)Find the critical value. Round the answer to at least two decimal places.
Critical value is
 
(c)Compute the test value. Round the standard deviations and 
F  score values to at least two decimal places.
F=
 
(d)Make the decision.

 

▼(Choose one) the null hypothesis.
 
 
 

 

(e)Summarize the results.

 

There is ▼(Choose one) that the variances are different.
