In a normal simple linear regression model you are given that
the variance of the error term is 4. Four observations are taken,
in which the X values are X=-2,1,2,3. Calculate the variance in the
estimate for the slope coefficient.
Given the general MULTIPLE linear regression model
with normal error, derive the LSE and MLE for the regression
coefficients and show they are equivalent.
I need help on this question. it needs to be for a
multiple linear regression model. thank you in advance.

State your hypotheses (e.g. HA: “calories will significantly
predict sodium”)
Create a scatterplot of the data. State if the scatterplot
appears to contain a linear relationship.
Conduct the analysis in SPSS. Include all of the important
outputs (e.g. ANOVA...

Why does the intercept estimator in simple linear regression
follow a normal distribution. Justify this by using the appropriate
assumptions of simple linear regression.
