Answer: (1500.66,1599.34)
Step-by-step explanation:
Confidence interval for population mean:
,where 
= Sample mean , n= Sample size, z* = critical two tailed z-value , 
= population standard deviation.
As per given , we have
n= 16
square feet
square feet
Critical z-value = 
Confidence interval for population mean:
Required confidence interval: (1500.66,1599.34)
Total coins = 10 ( 4 + 3 + 3 = 10).
The probability of picking a nickel first = 4/10 = 2/5 ( 4 nickels out of 10 total).
The probability of picking a dime second = 3/9 = 1/3 ( 3 dimes out of 9 coins left).
The probability of picking the third coin as a quarter = 3/8 ( 3 quarters out of 8 coins left).
The probability of picking all three in that order = 2/5 x 1/3 x 3/8 = 1/20
