Linear regression question If the range of the x-values are from x=100 to x=150, why might we be reluctant to

use our data to perform a hypothesis test on β0?

Solutions

Expert Solution

According to given problem;

We have only the X-values that are ranges from X=100 to X=150.and we don't have the value of dependent variable (say Y).

Now;

Therefore from provided picture we see that estimate of β depends also on dependent variable not only on explanatory variables.

Also;

from above picture we see that; the test statistic having a t-distribution .and Inn denominator of test statistic there is standard error of β which depends on dependent variables also.

Therefore from these we be reluctant to use our data to perform a hypothesis test on β0.

Linear Regression Linear regression is used to predict the value of one variable from another variable. Since it is based on correlation, it cannot provide causation. In addition, the strength of the relationship between the two variables affects the ability to predict one variable from the other variable; that is, the stronger the relationship between the two variables, the better the ability to do prediction. What is one instance where you think linear regression would be useful to you in...
