Answer:

Null hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is 40,000 miles.

Alternate hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is greater than 40,000 miles.

Explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.

Here is the deal: You can pay your college tuition at the beginning of the academic year or the same amount at the end of the ac
kirza4 [7]

Answer:

Deal, and the best option is to pay the same amount at the end of the academic year.

The reason for this is that if you have that amount in an interest bearing account, the money will earn interest, meaning that after paying the tuition at the end of the year, you will have the interest earned for yourself.

In other words, the present value of your money is the full value of your tuition, while the future value of your money is the value of the tuition plus the interest earned.

Besides, because the time value of money decreases as time passes, the amount you pay in tuition will represent less of your total income at then end of the academic year, than at the beginning.

Carrot Corporation, a C corporation, has a net short-term capital gain of $65,000 and a net long-term capital loss of $250,000 d
Tpy6a [65]

Answer:

$45,000

Explanation:

For computation of Carrot’s capital loss carryover to 2018 first we need to figure out some steps which is shown below:-

Step 1

Net Capital Loss = Net Short Term Capital Gain -2017 - Net Long Term Capital Loss -2017

= $65,000 - $250,000

= -$185,000

Here, Net Capital Loss amount $185,000 which is not deductible in year 2017, but can be carried back to the three preceding years i.e. 2014, 2015 and 2016

Step 2

Net Capital Loss is set off in preceding years = Net Short Term Capital Gain - 2014 + Net Short Term Capital Gain  2015 + Net Short Term Capital Gain - 2016

= $60,000 + $45,000 + $35,000

= $140,000

and finally

Amount of loss Carryover to 2018 = Net Capital Loss - Net Capital Loss is set off in preceding years

= $185,000 - $140,000

= $45,000

An increase in the fixed cost of working will ________ labor force participation and ________ hours of work (of those working be
Kaylis [27]

Answer: d. decrease; increase

Explanation:

If there is an increase in the Fixed Cost of Working, it leads to higher input costs in terms of labor when it comes to producing.

Producers will respond by trying to limit how much they spend on inputs by terminating the employment of some people as well as limiting new employment.

The Labor Force Participation Rate which refers to those active (both employed and unemployed) in the Labor Market will decrease because people might stop being active in the market as a result of the retrenchments and lack of opportunity.

The Producers however, will not demand more from the people still employed so that they may make better profits which will lead to an increase in the hours worked of those still employed.
