Answer: Point of estimation = 32.60
Margin of error = 1.175.
95% confidence interval would be (81.95,84.45).
Step-by-step explanation:
Since we have given that
n = 49
Average = $32.60
Standard deviation = $5
We need to find:
1) Point of estimation for the mean of the population:
2) At 90% level of confidence, z = 1.645
Margin of error would be
So, Margin of error = 1.175.
3) At 90% level of confidence, interval would be
Hence, 90% confidence interval would be (31.43,33.76).
