Suppose the proportion of the unemployed in a locality is 0.1. (i) ( 4 points).What is the probability of getting 25 or more unemployed people in a sample of n = 100, when you ignore the "Continuity Correction"? ( ii) ( 5 points). What is the probability in Q#3 (a)- (i) above when you apply the "Continuity Correction"? (b) (8 points). Suppose X ~ N ( µ , σ = 80.0 ), and suppose you require that P( ǀ x + - µ │< α ) = 0.95 where x + is the sample mean and the tolerance limit α is known.

You were told that the amount of time lapsed between consecutive trades on the new york stock exchange followed a normal distribution with a mean of 15 seconds. you were also told that the probability that the time lapsed between two consecutive trades to fall between 16 to 17 seconds was 13%. the probability that the time lapsed between two consecutive trades would fall below 13 seconds was 7%. what is the probability that the time lapsed between two consecutive trades will be between 14 and 15 seconds?
