. A social scientist would like to analyze the relationship between educational attainment and salary. He collects the following sample data, where Education refers to years of higher education and Salary is the individuals annual salary in thousands of dollars: education salary 3 41 4 46 6 59 2 49 5 68 4 43 8 91 0 40 A. Find the sample regression equation for the model: Salary = ?0 + ?1Education + ?. (Round intermediate calculations to 4 decimal...
Suppose you were presented with the following prediction regression equation: Yhat = 30,000 + 2,000 (X) where the dependent variable is annual salary and the independent variable is years on the job.

Matlab help thank you -Consider a person s yearly salary is 30k usd System 1: get 5% of your salary and put in a bank with 4% interest System 2:get 5% of your salary and match it with the same amount (another 5% from your employer) Calculate and plot over 30 years the amount of money you will get if you get 0% interest on system 2 ) for system 2 to become better than -Do another plot with different...
Given, y (estimated) = 9000 + 1.35x1 + 1.77x2, where y is salary, x1 is years of experience, and x2 is a dummy variable taking the value 1 for male and 0 for female. So, we can say that on average, salary is $1.77 higher for female employees than for male employees. true or false
