Answer:
The minimum sample size that should be taken is 62.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
If we want to be 90% confident that the sample mean is within 1 word per minute of the true population mean, what is the minimum sample size that should be taken
This is n when
. So





The minimum sample size that should be taken is 62.
Let one of the number be x
The other number will be x + 2
x + x + 2 = 15044
2x + 2 = 15044
2x = 15044 -2
2x = 15042
x = 7521
x + 2 = 7521 + 2 = 7523
The office number is 7521 and 7523
