A financial analyst wanted to estimate the mean annual return on mutual funds. A random sample of 60 funds' returns shows an average rate of 12%. If the population standard deviation is assumed to be 4%, the 95% confidence interval estimate for the annual return on all mutual funds is
A. 0.037773 to 0.202227
B. 3.7773% to 20.2227%
C. 59.98786% to 61.01214%
D. 51.7773% to 68.2227%
E. 10.988% to 13.012%
Answer: E. 10.988% to 13.012%
Step-by-step explanation:
Given;
Mean x= 12%
Standard deviation r = 4%
Number of samples tested n = 60
Confidence interval is 95%
Z' = t(0.025)= 1.96
Confidence interval = x +/- Z'(r/√n)
= 12% +/- 1.96(4%/√60)
= 12% +/- 0.01214%
Confidence interval= (10.988% to 13.012%)

Hwong could fill 12 packets of coffee in small boxes:
He has 10 boxes, so 10 x 12 = 120 packets total
Hwong's packets of coffee in the large boxes:
He can fit 50 packets into the boxes, so 120/50 = 2 large boxes and a remaining 20 packets of coffee
Therefore, Hwong can fit 12 packets of coffee to 1 small box and 8 packets to the other small box
