According to an almanac, 606 of adult smokers started smokng before turning 18 years old. (a) Compute the mean and standard deviation of the random varlable X, the number of smokers who started before 18 in 100 trials of the probability experiment. (b) Interpret the mean. (c) Would it be unusual to observe 90 smokers who started smoking before turning 18 years old in a random sample of 100 adult smokers? Why? O A. It is expected that in 50% of random samples of 100 adult smokers, 60 will have started ymoking before tuming 18. B. It is expected that in a random sample of 100 adult smokers, 60 will have started smoking after tuming 18. c. It is expected that in a random sample of 100 adult smokers, 60 will have started smoking before turning 18. (c) Would it be unusual to observe 90 smokers who started smoking before turning 18 years old in a random sample of 100 adult smokers? O A. No, because 90 is between u-20 and u+ 20. O B. Yes, because 90 is between u- 20 and + 20. OC. No, because 90 is greater than u + 20. D. Yes, because 90 is greater than u+ 20. O E. No, because 90 is less than u-20.
