The amounts of time employees of a telecommunications company have worked for the company are normally distributed with a mean o
Fynjy0 [20]

Answer:

a) 5.6 years

b) 0.4478

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 5.6 years

Standard Deviation, σ = 1.9 years

Sample size, n = 18

We are given that the distribution of amounts of time is a bell shaped distribution that is a normal distribution.

a) Mean of each sample.

The best estimator of the sample mean is the population mean itself. Thus, we have:

\mu_{x} = \mu = 5.6

Thus, the sample mean is 5.6 years.

b) Standard error

Formula:

S.E = \dfrac{\sigma}{\sqrt{n}}

Putting values, we have.

S.E = \dfrac{1.9}{\sqrt{18}} = 0.4478

Thus, the standard error is 0.4478.
