A frequency Distribution presents the number of adults aged 15-44 who watched the movie “Inside Out 2” at a local theater.  Age  Frequency 15-19 5 20-24 25 25-29 21 30-34 12 35-39 9 40-44 28 no need to round any of the following answers a. List the lower class limits in increasing order (separate with a comma) b. What is the class width? c. What is the class midpoint for class d. How many adults were there in this study?

Given the Frequency Distribution Table. Answer the following parts a-c.    Class  Class Midpoints Frequency 0-10 5 6 11-20 15 9 21-30 25 7 a. The sum( ∑ ) of the frequencies is b. The sum( ∑)  of the product of midpoints and frequencies is   (“Product of” means the “multiplication of” so the product of a and b means axb) c. The mean of the table is (rounded to two decimal places)

Three cars were tested for their fuel efficiency in miles per gallon (mpg) during a road trip. Arrange the cars in ascending order (smallest to greatest) based on their projected standard deviation without actually calculating s.   Car A: (30 mpg, 30 mpg, 30 mpg) Car B: (20 mpg, 15 mpg, 20 mpg) Car C: (10 mpg, 10 mpg, 50 mpg)     least , , largest standard deviation
