notsponge [240]

Answer:

s^2=1.32

Step-by-step explanation:

-This is a binomial probability distribution problem.

-Given that p=0.86 and n=11, the sample variance can be calculated using the formula:

\sigma^2=np(1-p)

#We substitute the given parameters in the formula to solve for variance:

\sigma^2=np(1-p)\\\\\\=11\times 0.86(1-0.86)\\\\=1.324\approx1.32

Hence, the sample variance is 1.32
