Let 'x' be a random variable that represents the length of time it
takes a student to write a term paper for Dr. Adam's Sociology
class. After interviewing many students, it was found that 'x' has
an approximately normal distribution with a mean of µ = 7.3 hours
and standard deviation of ơ = 0.8 hours.
