Answer:
β2 should have a positive sign
Explanation:
The regression equation is:
βwght = β0+β1cigs+β2faminc+μ
The equation tells us that the birth weight of a child is dependent on factors like cigarette consumption and family income.
β1 should have a negative sign because smoking during pregnancy has an adverse effect on birth weight. So there would be a negative correlation between birth weight and cigarette consumption.
β2 should have a positive sign. This is because while pregnant, a family with more income has the ability to provide better prenatal care and also better nutrition to the expectant mother. Therefore we have a positive correlation.
In a regression model concerning effects of smoking and income on infant birth weight, the coefficient 'b2' associated with family income is expected to be positive. Higher income levels are associated with improved prenatal care and nutrition, which contribute positively to infant birth weight.
The equation you presented is a form of a multiple regression model where 'bwght' is the dependent variable (infant birth weight), and 'cigs' and 'faminc' are independent variables representing the number of cigarettes smoked and family income, respectively. The terms 'b0', 'b1', and 'b2' are the model's parameters. In the context of this model, 'b2' represents the change in the infant's birth weight for a one-unit change in family income, holding all else constant.
The most likely sign for 'b2' is positive. This is because higher family income is generally associated with better access to prenatal care and nutrition which in turn positively impact the infant's birth weight.

The court selects a jury from a jury pool through a process known as _____.
Answer:
The average cost will be "$201". The further explanation is given below.
Explanation:
At May 31, FIFO LIFO Average cost
The ending inventory $220 $180 $201
Going to end Inventory Computation together under Quarterly inventory management system will be:
At $11 = $220
At $9 = $180
$10.06 = $201.2 i.e $201.
Answer: 1.15
Explanation:
Premium = 39%
Thor's share price = $42
The compensation to shareholders will be:
= $42 + ($42 × 0.39)
= $42 + $16.38
= $58.38
Loki's share price = $51
We then calculate the exchange ratio which will be:
= $58.38 / $51
= 1.15
Loki will need to offer an exchange rate of 1.15.
Answer:
Direct material= $340
Explanation:
Giving the following information:
Direct labor $540
Beginning work in process inventory $330
Ending work in process inventory $420
Cost of goods manufactured $1620
Manufacturing overhead $830
To calculate the direct material used in production, we need to use the following formula:
cost of goods manufactured= beginning WIP + direct materials + direct labor + allocated manufacturing overhead - Ending WIP
1,620= 330 + DM + 540 + 830 - 420
Direct material= $340
