A recent poll has suggested that 64 % of Canadians will be spending money - decorations, halloween treats, etc. - to celebrate Halloween this year. 20 Canadians are randomly chosen. and the number that will be spending money to celebrate Halloween is to be counted. This count is represented by the random variable X. Part (a) Compute the probability that 15 of these Canadians indicate they will be spending money to celebrate Halloween. P(X = 15) = E (use four decimals in your answer) Part (b) Compute the probability that between 9 and 14 of these Canadians, inclusive, indicate they will be spending money to celebrate Halloween. P(9 g X g 14) = E (use four decimals in your answer) Part (c) How many of the 20-Canadians randomly chosen would you expect to indicate they will be spending money to celebrate Halloween? Compute the standard deviation as well. E(X) = MK = E (use two decimals in your answer) SD(X) = 0X = E (use two decimals in your answer) Part (d) Compute the probability that the 12-th Canadian random chosen is the 8-th to say they will be spending money to celebrate Halloween. E (use four decimals in your answer) Preview My Answers Submit Answers
