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.

rosijanka [135]

Cryptocurrencies have rapidly increased in value, utility, and appeal since they were made widely available in 2009. Investors are interested in some of them since many retailers and business owners see them as viable options for generating returns and increasing store value. Governments are attempting to determine how to impose taxes and control them.

At the start of the cryptocurrency boom, Bitcoin appeared to be without a rival. Market capitalization for the sector was dominated by Bitcoin until, in a matter of weeks, Ethereum, Ripple, and other currencies sprinted to overtake it.

Although Bitcoin remains the market leader, some analysts are questioning whether cryptocurrencies are actually currencies in light of the industry's rapid growth. Some believe that even more significant changes may be on the horizon. the hypothesis that cryptocurrencies might eventually completely replace the money.

With its programmability and adaptability, Ethereum, a component of the blockchain ecosystem, offered not just a cryptocurrency but a wide range of use cases. Companies and entrepreneurs are leveraging it to develop new goods, technologies, and services.

The Ethereum blockchain and ecosystem provide the foundation for the decentralization of money as well as the developing "metaverse," which has the potential to unite our digital and physical selves.

Ne4ueva [31]

Answer:

D) has sunk costs of $6,000

Explanation:

Sunk cost is a cost which does not effect the financial decision, as this cost has already been incurred, and now it cannot be revoked.

Here maintenance cost is a regular expense which has to be incurred, and its not the cost which has already been incurred, same applies for operating cost.

Two years ago firm had spent $6,000 upgrading the equipment which was incurred earlier and now that cost cannot be revoked, further it will not lay any impact on any of the decisions made by the financial management.

Further amount to be spend of $5,000 has yet to be incurred and the decision to incur such cost can also be avoided, therefore it is not a sunk cost.

In this scenario D) has sunk sunk cost of $6,000

Grandiose Growth has a dividend growth rate of 20%. The discount rate is 15%. The end-of-year dividend will be $3 per share. Wha
11111nata11111 [884]

Answer:

The present value of dividend to be paid at the end of year 1, year 2, and year 3 are $2.60, $2.95, and $2.84 respectively.

Explanation:

The end of the year dividend is $3 per share.

The dividend growth rate is 20%.

The discount rate is 15%.

PV of dividend to be paid at the end of year 1

= \frac{end\ of\ the\ year\ dividend}{(1+discount\ rate)^n}

= \frac{3}{(1 + .15)^1}

= \frac{3}{1.15}

=$2.60

PV of dividend to be paid at the end of year 2

=\frac{end\ of\ the\ year\ dividend}{(1 + discount\ rate)^n}

=\frac{3\times (1+.20)}{(1+.15)^2}

=\frac{3.60}{1.322}

=$2.72

PV of dividend to be paid at the end of year 3

=\frac{end\ of\ the\ year\ dividend}{(1 + discount\ rate)^n}

=\frac{3\times (1+.20)^2}{(1+.15)^3}

=\frac{4.32}{1.52}

=$2.84

This means that the total income that Ron has as a result of this transaction is the $21,000 for services.

Ron's basis will therefore be;

= Cattle basis + Income from services rendered

= 6,000 + 21,000

= $27,000
