The data show the list and selling prices for several expensive homes. Find the regression equation, letting the first variable
be the independent (x) variable. Find the best predicted selling price of a home having a list price of $ million. Use a significance level of 0.05.
1 answer:
Answer:
The best predicted selling price of a home having a list price of $22 million is $20.52 million.
Step-by-step explanation:
The missing data is:
List price (<em>x</em>) (millions of $)
(1) 1.6 (2) 4.2 (3) 2.1 (4) 1.6 (5) 2.3 (6) 4
Selling price (<em>y</em>) (millions of $)
(1) 2 (2) 4.6 (3) 1.8 (4) 1.9 (5) 2.4 (6) 3.6
Use Excel to perform the regression analysis.
The significance level is, <em>α</em> = 0.05.
The regression output is attached below.
The regression equation is:
The value of <em>t</em>-statistic is:
<em>t</em> = 0.676.
The <em>p</em>-value is:
<em>p</em>-value = 0.536
Compute the predicted selling price of a home having a list price of $22 million as follows:
Thus, the best predicted selling price of a home having a list price of $22 million is $20.52 million.

<span>
When, time passes, the height decreases.
When the time is 40 seconds (x = 40) the package reaches the ground and the height is 0.
Therefore, a reasonable domain for the function is:
0 ≤ x ≤ 40
Answer:
0 ≤ x ≤ 40
