Assume that a procedure yields a binomial distribution with n
trials and the probability of success for one trial is p. Use the
given values of n and p to find the mean μ and standard deviation
σ. Also, use the range rule of thumb to find the minimum usual
value μ−2σ and the maximum usual value μ+2σ.

Assume that a procedure yields a binomial distribution with n
trials and the probability of success for one trial is p. Use the
given values of n and p to find the mean μ and standard deviation
σ. Also, use the range rule of thumb to find the minimum usual
value μ−2σ and the maximum usual value μ+2σ. Round your answer to
the nearest tenth, if necessary. In an analysis of the 1-Panel TCH
test for marijuana usage, 300 subjects...

Assume that a procedure yields a binomial distribution with n
trials and the probability of success for one trial is p. Use the
given values of n and p to find the mean mu and standard deviation
sigma. Also, use the range rule of thumb to find the minimum usual
