Question 4-10

4. (2 marks) The number of unemployed persons with the largest residual an inflation rate of 1.973%, and the number of unemployed persons was 157 (in thousands). Calculate the value of the residual. Type your answer with 3dp 1.282 x 5. (2 marks) The absolute value of the test statistic for testing the slope of the regression line is: -0.012 x (3dp) with degrees of freedom equal to: 29 X (integer). 6. (1 mark) The p-value for testing the slope of the regression line is less than 0.05. False c x 7. (2 marks) Select the most appropriate conclusion to the question \"Is the number of unemployed persons (in thousands) a useful predictor for inflation rate ( %)?". There is not enough evidence to indicate that the number of unemployed persons (in thousands) is a useful predictor of inflation rate (%). x 8. (1 mark) The correlation is: 0.764 x (3dp - remember to include a negative sign if appropriate) 9. (2 marks) Use the regression equation to predict inflation rate (%) for the number of unemployed persons of 139 (in thousands) (3dp): 254.039 3' 10. (3 marks) We are 95% confident that for extra increase in the number of unemployed persons (in thousands), the average inflation rate is expected to decrease v between -0.004 x % (lower limit) and 0.004 x % (upper limit). Type your answers with 3dp
