State with brief reason whether the following statements are true, false, or uncertain:a. In the presence of heteroscedasticity

OLS estimators are biased as well as inefficient.b. If heteroscedasticity is present, the conventional t and F tests are invalid.c. In the presence of heteroscedasticity the usual OLS method always overestimates the standard errors of estimators.d. If residuals estimated from an OLS regression exhibit a systematic pattern, it means heteroscedasticity is present in the data.e. There is no general test of heteroscedasticity that is free of any assumption about which variable the error term is correlated with.f. If a regression model is mis-specified (e.g., an important variable is omitted), the OLS residuals will show a distinct pattern.g. If a regressor that has nonconstant variance is (incorrectly) omitted from a model, the (OLS) residuals will be heteroscedastic.

A product priced at $5 has annual sales of 1,000 units. When price is reduced to $4, quantity increases to 1,250 units. Other th
AURORKA [14]

Answer:

Unitary

Explanation:

Price elasticity of demand is demand is defined as a measure of how sensitive quantity of a product demanded is sensitive to changes in price.

Usually an increase in price results in a reduction in quantity demanded, and reduction in price results in an increase in quantity demanded.

Using the midpoint method of calculating price elasticity

Price elasticity = (change in quantity demanded) ÷ (change in price)

Change in quantity demanded = (1000-1250)/(100+1250)/2

Change in quantity demanded = -0.2222

Change in price = (5-4) / (5+4)/2

Change in price = 0.2222

Price elasticity = -0.2222 ÷ 0.2222 = -1

Therefore price elasticity is unitary.

Unitary elasticity means that a a percentage change in price results in equal percentage change in quantity demanded

Mr. Zee worked 48 hours during the week ended January 18, 2019. He is paid $12 per hour and is paid time and a half for all hour
lapo4ka [179]

Answer:

=$524.81

Explanation:

Net pay = Earning -taxation

Calculating net pay: hour pay x hours worked

 = $12 x 40

 = $ 480

overtime pay =12 +(50/100x12)x 8

  =(12+6)x8

  =144

total earnings = $144+$ 480= $624

less deduction

social and medicare rate = 7.65 percent

federal and state unemployment rate =0.6 +3.8%

total deduction = 7.65 +O.6 + 3.8= 12.05 %

Actual deduction =12.05/100 x 624= 75.19

Net pay = $624- $75.19

 =$524.81

Overton Company has gathered the following information. Units in beginning work in process 20,300 Units started into production
storchak [24]

Answer:

a. Materials = 206,000 units and Conversion costs = 196,040 units

b. Materials = $0.50 and Conversion costs = $2.65

c. Costs to units transferred out = $570,465 and Costs to units in process =  $59,511

Explanation:

a. Calculation of Equivalent Units of Production for Materials and for Conversion costs

Units Completed and Transferred  = Units in beginning work in process + Units started into production - Units in ending work in process

                                                          = 20,300 +  185,700 - 24,900

                                                          = 181,100

<u>Materials </u>

Units Completed and Transferred (181,100 × 100%) =    181,100

Units in Ending Work in Process (24,900 × 100%)   =    24,900

Equivalent Units of Production                                  = 206,000

<u>Conversion costs </u>

Units Completed and Transferred (181,100 × 100%) =    181,100

Units in Ending Work in Process (24,900 × 60%)    =     14,940

Equivalent Units of Production                                  =  196,040

b. Calculation of  the unit costs of production.

Unit costs of production = Total Cost / Equivalent Units of Production

Materials = $103,000 / 206,000

               = $0.50

Conversion costs = ($333,306 + $186,200) / 196,040

                             = $2.65

Total Unit Cost = $0.50 + $2.65

                         = $3.15

c. Assignment of costs to units transferred out and in process.

Costs to units transferred out = 181,100 × $3.15

                                                 = $570,465

Costs to units in process

Materials  ($0.50 × 24,900)             = $12,450

Conversion costs  ($3.15 × 14,940)  = $47,061

Total Cost                                         =  $59,511

Unemployment would cause an economy to Group of answer choices produce outside its production possibilities frontier. produce in
bagirrra123 [75]

Answer:

The correct answer is: produce inside its production possibilities frontier.

Explanation:

The production possibility frontier shows the maximum possible combination of two goods that an economy can produce using all the available resources and state of technology.

Unemployment in an economy means that all the available resources are not being completely used. So, the economy will operate at a point inside the production possibility curve.

Production at this point will be feasible but allocatively inefficient.
