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)
