Answer:

lower range 33.822 years

upper range 38.178 years

Explanation:

step 1:

48 -1 = 47

step 2:

(1 - 95%) / 2 = 0.025

step 3:

we look at the T distribution table for degrees of freedom (df) = 47, and α = 0.025; = 2.0117

step 4:

divide sample standard deviation by square root of sample size

7.5 years / √48 = 7.5 / 6.9282 = 1.0825

step 5:

multiply results from step 3 and 4

2.0117 x 1.0825 = 2.178

step 6:

for the lower range, subtract step 5 from sample mean

36 - 2.178 = 33.822

step 7: for the upper range, add step 5 with sample mean

36 + 2.178 = 38.178

Pani-rosa [81]

Answer:

There are no options listed, but what I can tell you for sure is that John's actions were both unethical and illegal.

What John did is unethical because it is not moral and it goes against all the principles that guide professional conduct. John also did something illegal because he was an accomplice in committing fraud against the company. He knowingly benefited from the accountant's illegal actions, and that is basically the legal definition of an accomplice to a crime.

As you read the business news, you come across an advertisement for a bond mutual fund – a fund that pools the investments fro
Alika [10]

Answer:

Follows are the solution to this question:

Explanation:

Follows are the two ways of describing its high return:

Firstly, the mutual fund is invested in pretty unstable debt and is reciprocating with greater yields for taking a risk.

Secondly, during every decrease in bond yields, the finance kept bonds so the income on stocks exceeded this same rate of interest significantly. Remember that bond costs skyrocket as interest rates drop as well as give the purchaser an investment income. Because once interest rates are now close to zero, it's also likely that they could increase as well as the owners would then lose their money. Its high return could be due to a drop in interest rates, and not only will it not be replicated, but the low or even low return will almost definitely be followed by either a rise in interest rates.
