Answer:
(351.04, 368.96)
Step-by-step explanation:
Given that population mean= 360
Std devitaion = 4
margin of error = 2.5%= 0.025
Since population std deviation is known we can use Z critical value
For two tailed critical value for 2.5% would be
2.24
Margin of error = ±Critical value*std deviation
= ±2.24(4)
= ±8.96
Confidence interval =(Mean - margin of error, mean + margin of error)
=
First, I will made 4 1/2 into the decimal which is 4.5. Then, I add 6 with 4.5 to find the total fabric that Belinda will buy which is 10.5 in total. As a result, Belinda buys total 10.5 white and red fabrics.
