School of Mathematical SciencesMAT3024/ August 2020Page 1of 12Question 1 A social researcher is interested in the relationship between income and happiness. A survey involving 498 people whose income ranges from \$15k to \$75k, and ranking of their happiness on a scale from 1 to 10, has been collected. The average income is \$44,669.02.A simple linear regression model has been fitted to the dataset. The results of the regression analysis (income in \$’000) are shown below.

(a)Identify the dependent variable and independent variables in this case.

(b)State the fitted model.

(c)Perform a hypothesis testing to see if there is a linear relationship between income and happiness.

(d)Find a 95% CI on the mean happiness if the income is \$45k and the sum of squares of axis 150044.4.

(e)Suppose we wish to predict the happiness of a person given that his income is \$45k. Give a point estimate of happiness. Find a 95% prediction interval on the happiness.

(f) Compare and explain the difference between the two intervals obtained in parts (d) and (e).
