Answer:
Monthly Interest rate = 0.475%
EAR = 5.85%
Explanation:
a.
APR = 5.7%
Monthly Interest rate = APR / n
Monthly Interest rate = 5.7% / 12
Monthly Interest rate = 0.475%
b.
APR = 5.7%
m = 12
EAR = [ ( 1 + (APR / m))^m] - 1
EAR = [( 1 + (0.057 / 12))^12] - 1
EAR = [( 1 + 0.00475 )^12] - 1
EAR = [( 1.00475 )^12] - 1
EAR = 1.0585 - 1
EAR = 0.0585
EAR = 5.85%
True monthly rate of interest is 0.475%
EAR is 5.85%
Answer:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Explanation:
A confidence interval is a range of values, derived from the sample statistics, which may include the value of an unknown population parameter.
A 95% confidence interval indicates that between 152 of 160 samples (95%) of the same population will produce confidence intervals that will contain the population parameter.
It also means that we have a 95% confidence that the average (average amount) is among the resulting amounts obtained.
Logically, option "D" is missing the final part. This would be: D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $ 15.
This is the only true option, since the test is based on a sample of only 160 households, the entire population of households cannot be included.
Hence, the correct option is:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Answer:
$1,282.80
Explanation:
The PMT formula is used for this question. The attachment is shown below:
The NPER shows the time period
Given that,
Present value = $300,000 - $30000 = $270,000
Future value = $0
Rate of interest = 4% ÷ 12 months = 0.33%
NPER = 30 years × 12 months = 360 months
The formula is shown below:
= PMT(Rate;NPER;-PV;FV;type)
The present value come in negative
So, after solving this, the answer is $1,282.80
