Answer:
57.60
Step-by-step explanation:
If the coat is marked up 28%, then the cost is increased by 28% to produce the selling price.
SP = 45 + 28/100 * 45
SP = Selling Price
SP = 45 + 28*45 / 100
SP = 45 + 1260 / 100
SP = 45 + 12.60
SP = 57.60
Answer: The selling price is 57.60

Step-by-step explanation:
Margin of error = critical value × standard deviation
We aren't given the critical value or any information to calculate it, so we need to make some assumptions. Assuming the data set is large enough to be approximated as normal, and that the confidence level is 95%, then the critical value is 1.96.
ME = 1.96 × 9.5
ME = 18.62
You may choose to round 1.96 to 2, in which case the margin of error is:
ME = 2 × 9.5
ME = 19
