Inessa05 [86]

(B) 4 hr is the correct answer.

<h3>Explanation :</h3>

★ Speed of body is defined as the ratio of distance travelled to the time taken $.$

speed = distance/time

Given that,

distance = 56 miles

speed = 14 miles per hour

By substituting the values, we get

⭆ time = distance/speed

⭆ time = 56/14

⭆ time = 4 hr

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.
