Answer:
(0.6430, 0.8170)
Step-by-step explanation:
Given that during a recent drought a water utility in a certain town sampled 100 residential water bills and found out that 73 of the residences had reduced their water consumption over that of the previous year.
Sample size n = 100
Sample proportion p = 
q = 1-p = 0.23
Std error of proportion = 
95% Z critical value = 1.96
Margin of error = 
Confidence interval = sample proportion ±margin of error
0.642983946
0.817016054

- sticker: $12,620
- dealer's cost: $10,712
<h3>
Step-by-step explanation:</h3>
The total cost of options is the sum of their individual costs.
total options = $542 +140 +318 +580 = 1580
The sticker price is ...
sticker price = base price + total options + destination charge
= $10600 +1580 +440
sticker price = $12,620
The dealer cost is ...
dealer cost = 82% × base price + 100% × total options + destination charge
= 0.82·$10600 +1580 +440
dealer cost = $10,712
