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.
