Consider the following binomial probability distribution:
P(x)=(10/x) (0.65)^x (0.35)^10-x, x=0,1,2,3...,10
a. is x a discrete or a continuous random variable?
b. calculate the mean of the binomial probability distribution.
c. calculate the standard deviation of the binomial probability distribution.
*** Please explain how you got the answer**
Thank you
I don't understand how P(x) = 10/x relates to the rest of the problem, especially since you allow one of the values to be zero. Ignoring that:
Since you have 11 distinct values (0, 1, ..., 10), it is a discrete function.
Mean = n · p = 11 x 0.65 = 7.15
Standard deviation = √ (n · p · q) = √ (11 · 0.65 · 0.35) = 1.545
