Question

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 are tested and the probability of a positive result is 0.48, so n=300 and p=0.48.

Answer 1

Here Mean, standard deviation, minimum value and maximum value calculation.

Mean = 144

Standard deviation =  8.65

Minimum value = 126.7

Maximum value = 161.3
