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 **i**th 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**

A simple random sample
of 16 adults drawn from a certain population of adults yielded a
mean weight of 63kg. Assume that weights in the population are
approximately normally distributed with a variance of 49. Do the
sample data provide sufficient evidence for us to conclude that the
mean weight for the population is less than 70 kg? Let the
probability of committing a type I error be .01.

hypotheses, indicate the claim
