Document Summary
Page 1 of 5: the following numbers xi, i = 1, . , 18, represent a sample of size n = 18 from a given population. 2. 1987 2. 5252 2. 8462 2. 2722 2. 2026 2. 0153: compute the sample median and fourth spread and nd eventual outliers, knowing that. Assume that 40% of all the cars that arrive need service. Page 3 of 5: using the result of points b) and c) nd the probability that exactly n cars arrived in a given day given that exacly n cars needing service arrived that day. Interpret your result in term of the number of car not needing service that arrive in a day: in atlanta there are 2. 000. 000 families. Among them 40. 000 do not report correctly their incomes. The irs select a sample of 200 families and controlls their tax returns. Write a formula for the probability that x = 4.
