Answer:

  • Iced tea is $4.50 per gallon
  • Lemonade is $4.75 per gallon

Step-by-step explanation:

<u>Price</u>:

  • Iced tea = x, lemonade = y

<u>Equations</u>:

  • 2x + 3y = 23.25
  • 5x + 4y = 41.50

<u>Multiply the first equation by 5 and the second equation by 2 and subtract to eliminate x:</u>

  • 5(2x + 3y) - 2(5x + 4y) = 5(23.25) - 2(41.50)
  • 10x + 15y - 10x - 8y = 33.25
  • 7y = 33.25
  • y = 33.25/7
  • y = 4.75

<u>Use the first equation to find x:</u>

  • 2x + 3(4.75) = 23.25
  • 2x = 23.25 - 14.25
  • 2x = 9
  • x = 9/2
  • x = 4.50

Iced tea costs $4.50 per gallon

Lemonade costs $4.75 per gallon

Consider the population regression of log earnings [Yᵢ, where Yᵢ= ln(Earningsᵢ)] against two binary variables:
puteri [66]

Answer:

A) allows the population effect on log earnings of being married to depend on gender

Step-by-step explanation:

The regression equation of a dependent variable based on two or more independent variables is of the form:

Y=b_{0}+b_{1}X_{1} +b_{2}X_{2}+b_{3}X_{1}X_{2}

Here,

<em>Y</em> = dependent variable

X_{1} and X_{2} = independent variables

X_{1}X_{2} = interaction term

b_{1},\ b_{2}\ and \ b_{3} = regression coefficients.

If there is a significant interaction effect present then this implies that the effect of one independent variable (X_{1} orX_{2} ) on the dependent variable (<em>Y</em>) differs every time with different value of the other independent variable  (X_{1} orX_{2} ) .

The provided regression equation is:

Y_{i}=\beta _{0}+\beta _{1}D_{1i}+\beta_{2}D_{2i}+\beta _{3}D_{1i}D_{2i}+u_{i}

Y_{i} = dependent variable

D_{1i} and D_{2i} = independent variables

In this case the interaction term is defined as follows:

The effect of being married on log earnings is dependent on different values of the variables D_{2i}, i.e. the gender of the i^{th}person.

Thus, the correct option is (A).
