# Question: The following data represent the homework scores for the material

The following data represent the homework scores for the material on Polynomial and Rational Functions in Sullivan’s College Algebra course.

(a) Construct a relative frequency distribution with a lower class limit of the ﬁrst class equal to 30 and a class width of 10.

(b) Draw a relative frequency histogram of the data.

(c) Determine the mean and median score.

(d) Describe the shape of the distribution based on the results from parts (b) and (c).

(e) Determine the standard deviation and interquartile range.

(f ) What is the probability a randomly selected student fails the homework (scores less than 70)?

(g) What is the probability a randomly selected student earns an A or B on the homework (scores 80 or higher)?

(h) What is the probability a randomly selected student scores less than 30 on the homework?
