Answer to Problem 54E

The quadratic regression equation for the given data ofBroadway Season Revenue is y=0.723x2+26.726x+290.914 .

Explanation of Solution

Given information:The table given below shows the gross revenue for Broadway season in different years:

    Broadway Season Revenue
    YearAmount ($ millions)
    1994406
    1999603
    2004769
    2005862
    2006939
    2007938

Calculation:

Consider that x=0 represents year 1999, x=1 represents year 2000, x=2 represents year 2001 and so on.

To find the natural logarithm regression equation of the given data, use graphing calculator.

Step 1: Press STAT1 keys to enter the given data.

Step 2: List the input values 4, 9, 14, 15, 16 and 17 in the L1 column.

Step 3: List the input values 406, 603, 769, 862, 939 and 938 in the L2 column.

Step 4: Press the keystrokes STAT5ENTER to find line of quadratic regression and again press ENTER key.

  y=0.723x2+26.73+290.914

Therefore, the quadratic regression equation for the Broadway Season Revenue is y=0.723x2+26.726x+290.914 .

    2004769
    2005862
    2006939
    2007938

Graph:

From part (a), the quadratic regression equation for the Broadway Season Revenue is y=0.723x2+26.726x+290.914 . Now, to make the scatter plot, follow the steps using graphing calculator.

Step 1: Press 2ndY= and make sure that Plot 1 is ON. Choose the scatter plot icon in type.

Step 2: Press GRAPH key. Set the window at [0,20] by [300,1000] .

Step 3: Press the keystrokes STAT5ENTER2nd1,2nd2,VARS11ENTER and. Now, press the GRAPH key to plot the graph as shown below.

Answer to Problem 54E

The amount of gross revenue for the Broadway Season in year 2012 is 1228.15 millions of dollars.

Explanation of Solution

Given information:The table given below shows the gross revenue for Broadway season in different years:

    Broadway Season Revenue
    YearAmount ($ millions)
    1994406
    1999603
    2004769
    2005862
    2006939
    2007938

Calculation:

From part (a), the quadratic regression equation for the Broadway Season Revenue is y=0.723x2+26.726x+290.914 .

Consider that x=0 represents year 1999, x=1 represents year 2000, x=2 represents year 2001, x=17 represents year 2007and so on. The year 2012 is represented by x=22 .

Substitute 22 for x in the quadratic regression equation.

  y=0.723(22)2+26.73(22)+290.914y=1228.15

Therefore, the amount of gross revenue for the Broadway Season in year 2012 is 1228.15 millions of dollars.

(d)

To determine

To find:The linear regression for the data given in the table for the gross revenue of Broadway season and the amount of revenue in 2012.

Answer to Problem 54E

The linear regression equation for the Broadway Season Revenue is y=41.87x+229.48 and the approximate revenue in year 2012 is $1150 million.

Explanation of Solution

Given information:The table given below shows the gross revenue for Broadway season in different years:

    Broadway Season Revenue
    YearAmount ($ millions)
    1994406
    1999603
    2004769
    2005862
    2006939
    2007938

Calculation:

To find the linear regression equation of the given data, use graphing calculator.

Press the keystrokes STAT4ENTER .

  y=41.87x+229.48

Now, substitute 22 for x in the above equation to find the revenue in 2012.

  y=41.87(22)+229.48y=1150.62

Therefore, the linear regression equation for the Broadway Season Revenue is y=41.87x+229.48 and the approximate revenue in year 2012 is $1150 million.
