Answer:
The standard deviation of the sample mean differences is _5.23_
Step-by-step explanation:
We have a sample of a population A and a sample of a population B.
For the sample of population A, the standard deviation 
is
The sample size 
is:
.
For the sample of population B, the standard deviation 
is
The sample size 
is:
.
Then the standard deviation for the difference of means has the following form:
Finally
You have not provided the choices, therefore, I cannot give exact answers.
However, I will try to help you out with some information.
A cylinder is a three-dimensional geometric solid.
It has the same shape as a soda can.
<u>As for the bases, they have the following properties:</u>
1- the bases have a circular (disc) shape
2- the bases are congruent to each other
3- the bases are parallel to each other
Hope this helps :)
