Service time for a customer coming through a checkout counter in a retail store is a random variable with the mean of 1.0 minutes and standard deviation of 3.0 minutes suppose that the distribution of service time is fairly close to a normal distribution. suppose there are two counters in a store, ni = 47 customers in the first line and n2 48 customers in the second line. find the probability that the difference between the mean service time for the shorter line xi and the mean service time for the onger one x2 is more than 0.6 minutes. assume that the service times for each customer can be regarded as independent random variables. round your answer to two decimal places (e. g. 98.76) p0.1134 the absolute tolerance is +/-0.01
