Suppose speeds of vehicles traveling on a highway have an unknown distribution with mean 63 and standard deviation 4 miles per h
Mashutka [201]

Answer:

The standard deviation for the sample mean distribution=0.603

Step-by-step explanation:

We are given that

Mean,\mu=63

Standard deviation,\sigma=4

n=44

We have to find the standard deviation for the sample mean distribution using  Central Limit Theorem for Means.

Standard deviation for the sample mean distribution

\sigma_x=\frac{\sigma}{\sqrt{n}}

Using the formula

\sigma_x=\frac{4}{\sqrt{44}}

\sigma_x=\frac{4}{\sqrt{2\times 2\times 11}}

\sigma_x=\frac{4}{2\sqrt{11}}

\sigma_x=\frac{2}{\sqrt{11}}

\sigma_x=0.603

Hence, the standard deviation for the sample mean distribution=0.603
