Answer:
[tex]s^2=1.32[/tex]
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:
[tex]\sigma^2=np(1-p)[/tex]
#We substitute the given parameters in the formula to solve for variance:
[tex]\sigma^2=np(1-p)\\\\\\=11\times 0.86(1-0.86)\\\\=1.324\approx1.32[/tex]
Hence, the sample variance is 1.32
