77% of workers know what their CEO looks like. You randomly select six workers and ask each if they know what their CEO looks like. Complete parts (a) through (d) below. (a) Find the mean of the binomial distribution. μ=
(b) Find the variance of the binomial distribution. σ^2=
(c) Find the standard deviation of the binomial distribution σ=
(d) interpret the results the context of the real-life situation.
On average out of 6 workers know what their CEO looks like. The standard deviation is , so in most samples of six workers, the number of workers know what their CEO looks like would differ from the average number by no more than .
