A random sample of teenagers was taken and the number of hours each worked was recorded along with the age of the car that each usually drove. The table below shows the results from the study. Age of car usually driven-Test Hours worked per Less than week Under 15 15-25 Over 25 4 7 36 28 4-8 8 17 17 Over 8 14 16 17 X² = 8.25774 p=0.08258 df = 4 Test the hypothesis that the age of the car driven is associated with the number of hours worked per week, using a significance level of 0.10. Choose the correct decision regarding the null hypothesis and decision. Refer to the computer output above.
