Assume that about 24% of those called will find out an excuse (work, poor health, travel out of town, etc.) to avoid jury duty. If 10 people are called for jury duty, find out the standard deviation σ of the probability distribution for the number of people available for jury duty. Round your answer to three decimal places.
Answer
a. σ = 7.600
b. σ = 1.824
c. σ = 2.583
d. σ = 1.351
e. σ = 8.621
