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.
The expected return for stock A and B is 8.55% and 15.11% respectively.
<h3>What is the Expected return?</h3>
= (Probability of Recession × Return during recession) + (Probability of normal × Return during normal) + (Probability of boom × Return during boom)
Expected return for stock A:
= (0.20 * .05) + (0.57 * 0.08) + (0.23 * 0.13)
= 0.0855
= 8.55%
Expected return for stock B:
= (0.20 * 0.20) + (0.57 * 0.09) + (0.23 * 0.26)
= 0.1511
= 15.11%
Therefore, the expected return for stock A and B is 8.55% and 15.11% respectively.

Answer:
$977.93
Explanation:
This is a coupon paying bond. Using a financial calculator, input the following;
Time to maturity; N = 15
Coupon payment; PMT = 7.25% *1000 = 72.5
Face Value; FV = 1,000
Annual interest rate; I/Y = 7.5%
then compute the price of the bond, a.k.a present value; CPT PV = 977.93
Therefore, the price of the bond today is $977.93
