An animal activist group wonders if the average age a cat comes to the shelters in its county is the same as the average age for the whole state. The group randomly selected 44 cats from the 3 shelters in its county and found the sample mean age was 1.4 yrs. Assume a population standard deviation of 2.5 yrs. What is the point estimate?
Homework Answers
Solution :
Given that,
sample mean = 
= 1.4
Population standard deviation = 
= 2.5
Sample size n =44
point estimate= sample mean = = 1.4
point estimate= = 1.4

7. A group of university students are interested in comparing the average age of cars owned by students and the average age of cars owned by faculty. They randomly selected 25 cars that are own by students and 20 cars that are owned by faculty. The average age and standard deviation obtained from the students' cars are 6.78 years and 5.21 years, respectively. The sample of faculty cars produced a mean and a standard deviation of 5.86 years, and 2.72....
