Move to Problem: 12 Problem 1. (1 point) The Canadian Industry reports that impaired driving accounts for 26% of fatal vehicle accidents involving Canadian youths aged 15 to 19, secondary only to speeding as the highest cause of fatal vehicular accidents for Canadians aged 15 to 19 years of age. A recent inspection of n = 249 randomly chosen vehicle accidents that involved a Canadian between the ages of 15 and 19 years of age AND where a fatality occurred, was taken. It was found that 69 of these fatal vehicles accidents were caused by distracted driving. (a) Does these data suggest that distracted driving is now the leading cause of fatal vehicular accidents? Select the appropriate statistical hypotheses. O A. Ho p = 0.26 O B. Ho p 0.26 OC. c. Ho p=0.26 P O D. Ho p > 0.26 HA p>0.26 HA: p 0.26 OF. Ho 0.26 HA < 0.26 O G. Ho p=0.26 HA p 0.26 (b) Compute the value of the test statistic. Test Statistic = (use three decimals in your answer) (c) Which of the probability expressions below computes the P-value? O A. P(Z < Test Statistic) O B. P(T248 Test Statistic) C. P(Z > Test Statistic) D. P(Z Test Statistic) O E. P(T248> Test Statistic) F. P(T248 Test Statistic) * 2 O G. P(Z > Test Statistic) * 2 (d) Complete the interpretation of the P-value computed in part (c): Assuming Ho is ? , the probability of ?
