Answer:

11.611 +/- 3.013

Explanation:

3     3.5     4       6        7          8        8.5        12.5       15

7      17      19      12       19       22       28         20         28

difference

4      13.5    15     6       12        14        19.5        7.5         13

mean = 11.611

the standard deviation ⇒ 7.611² + 1.889² + 3.389² + 5.611² + 0.389² + 2.389² - 7.889² + 4.111² + 1.389² = 57.927 + 3.568 + 11.485 + 31.483 + 0.151 + 5.707 + 62.236 + 16.9 + 1.929 = 191.386/9 = √21.265 = 4.611

standard deviation = 4.611  1.918

confidence interval = mean +/- [(standard deviation/√9) x 1.96]

11.611 + [(4.611/3) x 1.96] = 11.611 + 3.013

11.611 - [(4.611/3) x 1.96] = 11.611 - 3.013

Larry’s Life Insurance Co. is trying to sell you an investment policy that will pay you and your heirs $32,000 per year forever.
Harman [31]

Answer:

$444,444.44

Explanation:

Larry's life insurance corporation is trying to sell an investment policy that will pay you and your heirs a total amount of $32,000 per year

The required return on this investment is 7.2%

= 7.2/100

= 0.072

Since the cash flow is a perpetuity then, the amount that will be paid for the policy can be calculated as follows

PV= C/r

= $32,000/0.072

= $444,444.44

Hence the amount of money that will be paid for the policy is $444,444.44

Question 433 pts Implementation of the law Group of answer choices is typically done by the members of Congress. is typically au
Eddi Din [679]

Answer:

Implementation of the law Group of answer choices requires judgment because laws are often very vague.

Explanation:

Originally, The Executive arm of government is supposed to implement the law while the congress which is also called the legislative arm enacts them.

However, It is necessary for the judiciary to interpret the laws since the executive arm tends to abuse their privileges thereby failing to implement the law.

The law is vague and is often subject to interpretation. The judges constitute a neutral body that balances power in government by passing judgement on erring officials and the entire citizenry thereby making implementation of the law possible.

kap26 [50]

Answer:

a. 24,000 unfavorable

Explanation:

Quantity Variance = Standard Price ( Actual Quantity - Standard Quantity Allowed)

             = $12 per pound  (8 lbs.*16,500 lbs-8 lbs.*16,000)

= $ 12 (132,000 lbs-130,000 lbs) = $ 12 (2000)= 24,000 unfavorable

It is unfavorable because the actual quantity used is more than the standard quantity allowed.

Quantity variance is obtained by multiplying the standard price with the difference in the actual quantity used and the standard quantity allowed.
