Question

The weights, in pounds, of the cats in an animal adoption center are normally distributed. If a random sample of cats is taken and the confidence interval is (7.9,12.7), what is the margin of error?

Give a numerical response for your answer. For example, if you found that the margin of error was 2, you would enter 2.

Answer 1

2.4

Explanation:

Given that :

The confidence interval = ( 7.9 , 12.7 )

The Margin of error M.O.E = Interval width/2

where;

The interval width = UCL - LCL

The interval width = 12.7 - 7.9

The interval width = 4.8

∴

The Margin of error M.O.E = 4.8/2

The Margin of error M.O.E = 2.4
