In testing the validity of a multiple regression model in which there are four independent variables, the null hypothesis is:.

H0 : β1 = β2 = β3 = β4 = 0

Step-by-step explanation:

The null hypothesis refers to a hypotheses that simply states that no relationship exists between two phenomenons that are being tested.

In testing the validity of a multiple regression model in which there are four independent variables, the null hypothesis is H0 : β1 = β2 = β3 = β4 = 0.

Multiply -1/4 with (d + 1)

Now, multiply 4 at both sides

Now, 4 and 4 gets cancelled out in LHS and in the RHS, we get 8

Now, take out the minus sign and flip the arrow symbol transpose -1 to the other side

Now, take 1 on the other side with a change in symbol.

So, the solution is -9.

Now for the graph, we have to draw a circle around -9 and draw an arrow facing the right. This is because d is greater than -9.

Answer:

> -9
