'Suppose Y follows binomial distribution with mean =10and variance of 7, what is the value of the probability of success, p? a.0.3 b 0.7 c.0.5 d.0'
Added by Kathleen G.
Step 1
Given that the mean is 10 and the variance is 7, we can set up two equations: np = 10 np(1-p) = 7 We can solve for p by substituting the first equation into the second equation: n(10)(1-p) = 7 10n - np = 7 10n - 10p = 7 10p = 10n - 7 p = (10n - 7)/10 We don't Show more…
