Question

5. Assume that procedure yields a binomial distribution with a trial repeatedS times (n -8). Use the biñomial formula to find the probability of 2 successes (x2) given that probabilityof success on a single trial is equal to 60%. A) 0.0326 B) 0.1951 C) 0.1213 D) 0.0413 6. Find the mean and standard deviation for the given above binomial distribution (n=8, p =0.6). 7, A computer salesman averages 2.75 sales per week ( = 2.75). Use the Poisson distribution to find the probability that in a randomly selected week the number of computers sold is at least 1 (one or more). Show the result of calculations and circle one D) 0.0639 C) 0.9415 B) 0.8647 A) 0.9361
