Hi,
A surgical technique is performed on eight patients. You are told that there is an 80% chance of success.
a) Construct a binomial distribution.
P = nCx*p= .8 and q = .2 and n = 8
b) Find the
mean = np =
variance = npq =
standard deviation of the probability distribution.
c) P(x = 6) == .2936 or 29.36%
d) P(x < 6) = 1 - P(x = 8) - P(x = 7) - P(x = 6)
= 1 - .1678 - .3355 - .2936 = .2031 or 20.31%
