The owner of Showtime Movie Theaters, Inc., would like to predict weekly gross revenue as a function of advertising expenditures
hoa [83]

Answer:

The predicted value of Revenue is $98.24.

Explanation:

The data provided is for the weekly gross revenue, the amount of television advertising and the amount of newspaper advertising.

Determine the regression equation developed to estimate the amount of weekly gross revenue based on television advertising using Excel.

Consider the Excel image for Summary Output for Weekly Revenue Vs. T.V. Adv.

The estimated regression equation with the amount of television advertising as the independent variable is:

<em>Revenue </em>= 89.31 + 1.27 <em>TVAdv</em>

Consider the Excel image for Summary Output for Weekly Revenue Vs. T.V. Adv. & News Adv.

The estimated regression equation with both television advertising and newspaper advertising as the independent variables is:

<em>Revenue </em>= 83.78 + 1.78 <em>TVAdv</em> + 1.47 <em>NewsAdv </em>

For TVAdv = $4.9 and NewsAdv = $3.9 predict the value of Revenue as follows:

\text{Revenue} = 83.78 + 1.78\ \text{TVAdv} + 1.47\ \text{NewsAdv}

             =83.78 + (1.78 \times 4.9) + (1.47 \times 3.9)\\\\=98.235\\\\\approx 98.24

Thus, the predicted value of Revenue is $98.24.

Aleks04 [339]

GDP is the sum of all final goods and services produced by an economy in a given period. In calculating GDP only the final goods and services that are traded are accounted for. Thus, household services that do not generate income are not accounted for in GDP, only productive activities. Therefore, in the long run the tendency is that the GDP analyzed by this issue will decrease, because when the unemployment rate increases, fewer workers will be employed in the productive sector. These people may substitute work for leisure or household chores, but this will not count in GDP.
