Q 1 - A nation job placement company is interested in developing a model that might be used to explain the variation in starting salaries for college graduates based on the college GPA. through a random sample of the clients with which this company has been associated. The following data were collected |GPA Starting Salary 3.20 $35,000 3.40 $29,500 2.90 $30,000 3.60 $36,400 2.80 $31,500 2.50 $29,000 3.00 $33,200 3.60 $37,600 2.90 $32,000 3.50 $36,000 Based on this sample information: (a). Calculate the correlation coefficient between these two variables. (b). Conduct a test of hypothesis to determine if there exists a correlation between the two variables in the population. Use a significance level of 0.05. determine the least squares regression model. Also, develop a scatter plot of the data and locate the regression line on the scatter plot. (c).
