Expert Solution

answers :

1. ) The assumptions of the simple linear regression is as the include is,.....

the option ( d ) is correct answer

the explanation is ,

Suspicions of Multiple Linear Regression. Numerous straight relapse investigation makes a few key presumptions: There must be a direct connection between the result variable and the free factors. ... Multivariate Normality– Multiple relapse expect that the residuals are ordinarily circulated.

2. ) Which of the following to the would not be the null hypothesis when performing to the chi-square test is,.....

the option ( c ) is correct answer.

the explanation is,

Which of the accompanying would not be an invalid theory when playing out a chi-square test?
Theory:
the Assumes that there is no relationship between the two factors.
the Assumes that there is a relationship between the two factors
these are So Correct answer is The line and segment factors are not related.
The R2 esteem from direct relapse means that the percent of the fluctuation of the reliant variable clarified by the , autonomous variable.
that is the There are four foremost suspicions which legitimize the utilization of direct relapse models for motivations behind derivation or expectation:
there is that is the There must be a straight connection between the result variable and the autonomous factors.This supposition expresses that the difference of blunder terms are comparable over the estimations of the free factors.
the inear relapse examination necessitates that the blunders among watched and anticipated qualities (i.e., the residuals of the relapse) ought to be regularly conveyed. This suspicion might be checked by taking a gander at a histogram or a Q-Q-Plot.
So finally the right answer is f) All aside from alternative c)

Suppose that normal error regression model (2.1) is applicable except that the error variance is not constant; rather the variance is larger, the larger is X. Does β1 = 0 still imply that there is no linear association between X and Y? That there is no association between X and Y? Explain.

Suppose that you performed a Simple Linear Regression of Height (equal the y-variable) on Weight (equal the x-variable). If the calculated r-value was equal to 0.9575, which of the following statements are appropriate parts of the interpretation of this r-value? Choose ALL that apply. A. Given that the r-value is 0.9575, the r-squared value will be 0.9785, rounded off to the 4th decimal place. B. Since this r-value is a positive number, the estimated y-intercept will also be a positive...
