Through this picture , please solve this questions - (questions are based on "Introductory Statistics" Writer Prem S. Mann. Chapter 13 and 14) Plz have a look before solving it.

a) What are the dependent and independent variables in this regression? Write the regression line? Is it

a multiple regression or simple regression?

b) Interpret the values of all coefficients and constants.

c) Do the hypothesis test for all independent variables at ? = 5% and 10%. Which variable is statically

insignificant?

d)Construct a 95% confidence for all independent variable?

e) Explain R-Squared and adjusted R squared in this regression. What is the value Standard deviation of

error in this above result?

g) Do F test and give the explanation if it's a multiple regression.

h) Explain RVF and AV plot. Run AV plot for all independent variables.

i)Construct scatter plot for all independent variables and mention whether it meets your expectations or

not.

Here is the Av Plot(Nitrogen application,yield of cotton) and rvf plot(Residuals, fitted values) -
