In a town’s study of its stray cats, a sample of stray cats had a mean weight of 7.3 lb. the study had a margin of error of 1.1 lb.
what is the interval estimate for the mean weight of the town’s stray cats in the form (lower limit, upper limit)?

show your work:

(6.2, 8.4)

Step-by-step explanation:

Mean weight of the cats = u = 7.3 lb

Margin of Error = E = 1.1 lb

The interval estimate is calculated by subtracting and adding the margin of error to the mean value as shown below:

( u - E, u + E)

Using the given values, we get:

(7.3 - 1.1, 7.3 + 1.1)

(6.2, 8.4)

Thus, the interval estimate for the mean weight of the town’s stray cats is (6.2, 8.4)

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

answer: it is d
