This assignment worth 20 points. Finding Probabilities using the Normal Distribution 1. A national study found that college students with jobs worked an average of 22 hours per week. The standard deviation is 9 hours. A college student with a job is selected at random. Find the probability that the student works for less than 4 hours per week. Assume that the lengths of time college student's work are normally distributed and are represented by the variable X. (3 points) Hint: Convert the normal distribution X to Standard normal using Z formula X-H Z = and then look the Z-values from the table and then find the probability
