Question

A random survey of applicants at 10 hospitals across the US yielded the following figures:

5156; 1587; 5867; 4525; 5734; 1653; 5342; 2357; 4118; and 5,342. what is the 99% EBM of the population mean?

Answer 1

Let X denote the figures of applicants at 10 hospitals across the US

denote the ith value of X

n = 10 (sample size)

denote the sample mean

Let s denote the sample standard deviation

For 99% EBM the level of significance() = 0.01

then critical value = = = = 3.2498

Answer: The 99% error bound(EBM) of the population mean is 1728.76
