Consider the experiments. Experiment 1: A study is done to determine which of two fuel mixtures allows a rocket to travel farthe

r over a period of time. Rocket A, which requires additional equipment to keep it stable, is used to test one fuel mixture, and rocket B is used to test the other. Both rockets are identical aside from their mass. The results indicate that rocket B traveled farther than rocket A over the same period of time. Experiment 2: A double-blind experiment is performed to test whether a new drug is effective in lowering blood pressure. A random sample of subjects with high blood pressure is assigned to two groups. One group receives the new drug and the other group does not. Neither group is permitted to take any other medications during the experiment or to change their lifestyles in any way. The results of the experiment show that the drug is effective in lowering blood pressure.
Identify the experiment in which confounding occurs and the reason for its occurrence.

a. Neither experiment has a confounding variable.
b. Experiment 1 has a confounding variable related to the fuel mixtures. Varying the fuel mixture could skew the results of the study and should be kept constant.
c. Experiment 2 has a confounding variable related to the type of experiment. A double-blind experiment may increase the risk of the placebo effect and possibly skew the results.
d. Experiment 1 has a confounding variable related to the mass of the rockets. Any variation in mass may cause a discrepancy in the distance traveled.
e. Experiment 2 has a confounding variable related to the subjects used. Choosing a sample of subjects with high blood pressure instead of individuals with different blood pressure levels may confuse the results.

Answer:

d. Experiment 1 has a confounding variable related to the mass of the rockets. Any variation in mass may cause a discrepancy in the distance traveled.

Explanation:

Both experiments have confounding variables.  But the reasons given for the occurrence of the confounder in experiment 2 do not justify (c) and (e) as correct answers.  By definition, confounders are factors other than the independent variable that cause differences in outcome.  For experiment 1, the different masses of the two rockets affect the independent variable (fuel mixture) being studied, and actually cause the discrepancy in the distance traveled as indicated in answer (d).  Other examples of confounders are placebo, weather, age, and experimenter bias which a double-blind can eliminate.

True or false: GAAP require end-of-period adjustments for the estimated bad debts in the period of the credit sale even though t
Feliz [49]

The given statement can be marked as true because the expense recognition principle requires an estimated expense be reported in the same period as the related credit sale rather than later when the customer is identified.

<h3>What is the GAAP?</h3>

The purpose of GAAP is to create a consistent and comparable method of accounting which ensures that a company's financial records are complete and homogeneous.

It also gives a complete picture of the company's financial position.

Without trade, the farmer produced and consumed 2 pounds of pork and 4 pounds of tomatoes and the rancher produced and consumed
Elis [28]

Answer:

the farmer gained 6 hours worth of production and the rancher gained 8 hours worth of production.

Explanation:

                 Labor Hours to Make 1 lb. of        lbs. Produced in 24 Hours

                  Pork                  Tomatoes              Pork            Tomatoes

Farmer        6                            3                       4                       8

Rancher     4                            4                       6                      6

If both decide to specialize in producing only one good, the farmer will produce 8 pounds of tomatoes per day and the rancher will produce 6 pounds of pork per day.

This way when the rancher trades 4 pounds of pork in exchange for 6 pounds of tomatoes, he is gaining 2 pounds of pork which is equivalent to 8 labor hours.

When the rancher trades 6 pounds of tomatoes in exchange for 4 pounds of pork, he is gaining 2 pounds of tomatoes which is equivalent to 6 labor hours.

A company paid $517,000 to purchase equipment and $16,700 to have the equipment delivered to and installed in the company's prod
Maslowich

Answer:

Using the units-of-production method, the amount of depreciation expense would the company report in the income statement prepared for the year-ended October 31, 2018 = $ 228899

Explanation:

Given

Acquisition Cost of Equipment = $ 517,000+ $ 16700= $ 533,700

Total units of production= 29,700 hours

Residual Value = $ 6700

Units of Production= 12,900 hours

Formula:

Depreciation per unit= (Cost -Salvage value) / Total units of production* Units of Production

Depreciation per unit= ($ 533,700 - 6700/ 29700)*12900

Depreciation per unit=($ 52,7000 / 29700)*12900

Depreciation per unit=( 17.744)*12900

Depreciation per unit= 228898.98= $ 228899

As units of production are given we do not need to calculate it for half year. The depreciation is calculated for units of production.
