Question
A sample of 10 blue-collar employees at a production plant was taken. Each employee was asked to assess his or her own job satisfaction (x) on a scale of 1 to 10. In addition, the numbers of days absent (y) from work during the last year were found for these employees. The sample regression line, given below, was estimated by least squares for these 10 2 data. Also found were x = 6.8, Σ (x₁ - x)² = 75.6, and SSE = 31. Complete parts a and b below. i=1 y₁ = 13.7 - 1.2x₁ Click to view the table of critical values of the Student's t distribution. Find the p-value. The p-value is 0.0007. (Round to four decimal places as needed.) Since the p-value is less than the significance level, satisfaction has a negative linear effect on absenteeism. reject The 95% prediction interval for the point runs from to (Round to two decimal places as needed.) Ho. This means that there is evidence that job b. A particular employee has job satisfaction level 4. Find a 95% interval for the number of days this employee would be absent from work in a year.
