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

Answer:
Option 1 - X = 9
Step-by-step explanation:
The solution to this equation, x - 15 = - 6
Solving the following,
Step 1: x - 15 = -6
Replace all the numerical values in one side and x digits on the other side
Step 2: x = -6+15
Step 3: x = 9
Therefore, the value of x is 9.
