Question

Suppose the total employee turnovers per year in a company are normally distributed. For a random sample of years, the confidence interval (84.50, 93.50) is generated. Find the error bound. Give just a number for your answer.

Answer 1

The error bound for the given confidence interval (84.50, 93.50) is calculated by subtracting the lower limit from the upper limit and dividing by 2, resulting in an error bound of 4.5.

Step-by-step explanation:

To find the error bound of a confidence interval, you take the upper limit of the interval and subtract the lower limit, then divide by 2. In the provided confidence interval (84.50, 93.50), the calculation would be:

(93.50 - 84.50) / 2 = 9 / 2 = 4.5.

So, the error bound is 4.5.
