Let's start by noting the total number of steps traveled was 2825, of which 1700 were taken before going to the store, so we must deduct them from the distance traveled to the store.
-19=5(×+9)
-19=5×+45
-19-45=5×
-64=5×
-64/5=×
×=-64/5
8 times because 8 times 8 equals 64
Answer: 5
Step-by-step explanation:
We know that the standard deviation of the sampling distribution of the means is given by :_
![SE=\sigma_x=\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=SE%3D%5Csigma_x%3D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Given : The average weekly earnings for employees in general automotive repair shops is
.
The standard deviation for the weekly earnings for such employees =
Now, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size
:-
![SE=\sigma_x=\dfrac{50}{\sqrt{100}}\\\\\Rightarrow\ SE=\dfrac{50}{10}\\\\\Rightarrow\ SE=5](https://tex.z-dn.net/?f=SE%3D%5Csigma_x%3D%5Cdfrac%7B50%7D%7B%5Csqrt%7B100%7D%7D%5C%5C%5C%5C%5CRightarrow%5C%20SE%3D%5Cdfrac%7B50%7D%7B10%7D%5C%5C%5C%5C%5CRightarrow%5C%20SE%3D5)
Hence, the standard deviation of the sampling distribution of the means of average weekly earnings for samples of size 100 = 5
