Answer:
$3450
Step-by-step explanation:
Here, P = $3000, N = 1.5 years, R = 10%

Amount of down payment
= $3000 + $450
= $3450
The given in this
problem are:
99% confidence level
N = 61
Mean = 2.0 kg
Standard deviation = 4.8
Z value for a 9%
confidence interval is 2.576
Confidence Interval = mean
± Z s/ sqrt n
= 2.0 ± 2.576(4.8/sqrt 61)
=2.0 ± 2.576 (0.6145770236779006736364371988794)
= 2.0 ± 1.5832
