Assume that about 24% of those called will determine an excuse (work, poor health, travel out of town, etc.) to avoid jury duty. If 10 people are called for jury duty, determine 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
