The margin of error of the random selection is 0.20
The given parameters are:
--- the sample size
--- the standard deviation
--- the mean
--- the confidence level.
The margin of error (E) is calculated as follows:
So, we have:
The z-value for 99% confidence level is 2.576.
Substitute 2.576 for z
Take square roots
Multiply
Approximate
Hence, the margin of error is 0.20

Answer:
Kayla = $20.14
Michael = $19.08
The Difference = 1.06
Step-by-step explanation:
<em><u>How to solve.</u></em>
First, you need to add up how much Kayla is paying for the video game, plus the 6% tax.
19.00 + 6% = 20.14
Then, you need to do the same with Michael's.
18.00 + 6% = 19.00
To find the difference between how much Kayla and Michael paid for their items, you need to subtract their total.
20.14 - 19.00 = 1.06
and the nearest cent would be 1.10.
