Answer:
Step-by-step explanation:
To get the new price of the car multiply the original price by the percent increase in decimal form +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.

Answer:
z-interval: (-1.64, 1.64)
90% Confidence interval: (7954,8446)
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= $8,200
Sample size, n = 225
Alpha, α = 0.10
Sample standard deviation, s = $750
90% Confidence interval:
Putting the values, we get,
z-interval: (-1.64, 1.64)
(7954,8446) is the required confidence interval.
