Answer:
A, B, C, D
Step-by-step explanation:
(A) Checking the Equal Variance Assumption, the appropriate technique to use is:
- The ANOVA (Analysis of Variance) F test
- Plot residuals against fitted values
(B) Checking the Normal Assumption, the appropriate techniques to use are:
- Test for Kurtosis & Skewness
- Kolmogorov-Smirnov Test
- Q-Q Plots (the graphical method) also known as Quantile Plot
- Do not use a histogram; it is not advisable
(C) Checking for Model Misspecification, the appropriate techniques to use are:
- The Ramsey Regression Specification Error Test; also called RESET
- The Davidson & MacKinnon J. Test
(D) Checking for dependent errors, the appropriate technique to use is:
- Plot residuals against time variables
A) The age of Theresa is 10 years 6 months old
B) Jonathan age is 24 years and 6 months old
<u>Solution:</u>
Given, Theresa is 14 years younger than her brother Jonathan.
Let the age of Theresa be "n" years
Then the age of Jonathan will be "n + 14" years
Together, their total age in years is 35
<em><u>A) Finding age of Theresa:</u></em>
Jonathan age + Theresa age = 35
n + 14 + n = 35
2n + 14 = 35
2n = 35 - 14
2n = 21
n = 10.5
So, age of Theresa is 10 years 6 months
<em><u>B) Finding age of Jonathan</u></em>
Now, we know that n = 10.5
Then Jonathan age = n + 14 = 10.5 + 14 = 24.5 years
So, Jonathan is 24 years and 6 months old
The coefficient 7 means that the length is 7 times the width
<h3>How to interpret the coefficient?</h3>
The given parameters are:
Width = x
Length = 7x
Area = 7x^2
We have:
Length = 7x
Substitute Width = x in Length = 7x
Length = 7 * Width
This means that the length is 7 times the width
