Suppose that for a given computer salesperson, the probability distribution of x = the number of systems sold in one month is given by the following table.
x 1 2 3 4 5 6 7 8
p(x) .06 .10 .11 .30 .30 .11 .01 .01
(a) Find the mean value of x (the mean number of systems sold).
Mean = 4.1
(b) Find the variance and standard deviation of x. (Round the answers to four decimal places.)
Variance = 2.03
Standard deviation = 1.4248
(c) What is the probability that the number of systems sold is within 1 standard deviation of its mean value?
P (μ - σ < x < μ + σ ) = ?
(d) What is the probability that the number of systems sold is more than 2 standard deviations from the mean?
P ( x < μ - 2σ or x > μ + 2σ) = ?
