Question 3 1) In linear/logistic regression, p value of an independent variable represents the probability that a certain null hypothesis about that variable is true. What is that null hypothesis? 2) Consider that you want to model the probability of people getting a job (y) based on their number of years of experience (X1) and whether someone has a foreign degree or not (X2 where no foreign degree is coded as 0 and foreign degree is coded as 1). You perform logistic regression in a statistical software and find the following values for the coefficients

B0=-26.52 B1=0.78 B2= - 0.567 a) Write down the logistic regression equation. b) Find the odds ratio of X1 and X2 and interpret. c) Calculate the estimated probability of getting a job for a person who has experience=35 years and a foreign degree.
