Problem #6: For drivers aged 20-24 there is a 34% chance of having a car accident in a one year period (based on data from the National Safety Council). In a sample of 11 drivers aged 20-24, let X be the number who have had an accident in the last year. Consider the following probability distribution for X. X P(x) 0 ? ? 2 ? 3 4 5 a 6 0.0894 7 0.0329 8 0.0085 9 0.0015 10 0.0001 11 0.0000 (a) Find the missing entry that is labelled as 'a'. (b) Suppose that a group of 11 drivers aged 20-24 are randomly selected, and 6 of them have had a car accident in the last year. Is this a significantly high number that would suggest that the given percentage of drivers aged 20-24 that have a car accident in a one year period (i.e., 34%) is not correct? Problem #6(a): answer correct to 4 decimals (A) No, because 0.0894 is greater than .05. (B) Yes, because 0.0894 is greater than . 05. (C) No, because 6 is not a lot more than expected. (D) No, because 0.1324 is greater than . 05. (E) Yes, because 0.1324 is greater than .05. (F) No, because 0.1735 is greater than .05. (G) Yes, because 0.1735 is greater than .05. (H) Yes, because 6 is a lot more than expected. Problem #6(b): Select
