Question 584876
Mean: 

mu = np = 122*0.24 = 29.28


So the mean is 29.3 (rounded to the nearest tenth)


-------------------------------------------------------

Variance:

sigma^2 = np(1-p) = 122*0.24(1-0.24) = 22.2528


So the variance is 22.3 (rounded to the nearest tenth)

-------------------------------------------------------

Standard Deviation:


sigma = sqrt(np(1-p)) = sqrt(122*0.24(1-0.24)) = 4.717287


So the standard deviation is 4.7 (rounded to the nearest tenth)
