the number of profits per store is normally distributed. if a random sample of stores is taken and the confidence interval is (104.25, 111.75), what is the error bound? give just a number for your answer. for example, if you found that the ebm was 2, you would enter 2.

Final answer:

The error bound for the given confidence interval of (104.25, 111.75) is found to be 3.75, which is half the difference between the upper and lower bounds.

Step-by-step explanation:

The error bound (EBM) or margin of error can be found by calculating half the difference between the upper and lower bounds of a confidence interval.

In this case, the confidence interval has the bounds of (104.25, 111.75).

To find the error bound (EBM), we calculate:

(Upper Bound - Lower Bound) / 2

= (111.75 - 104.25) / 2

= 7.5 / 2

= 3.75

Thus, the error bound for this sample of store profits is 3.75.
