An animal activist group wonder if the average age a cat comes to the shelter in its county is the same as the average age for the whole state. The group randomly selected 44 cats from the three shelters in its county and found the sample mean age was 1.4 years. Assume a population standard deviation of 2.5 years. Find the confidence interval for the mean age for cats that come to the shelters in that state.
