Intro to STATISTICS
Use the ogive to answer parts a) through d).
a) What is the cumulative frequency for a weight of 27.5 pounds? 40 b) What is the weight for which the cumulative frequency is 45? 30.5 c) How many beagles weigh between 22.5 and 29.5 pounds? 35 d) How many beagles weigh more than 30.5 pounds? 10
Use the frequency histogram to complete the following parts. (a) Determine the number of classes. (b) Estimate the greatest and least frequencies. (c) Determine the class width. (d) Describe any patterns with the data. ( Employee salaries)
(a) There are 7 classes. (b) The least frequency is about 30 The greatest frequency is about 270 (c) The class width is 10 (d) What pattern does the histogram show? About half of the employees' salaries are between $50,000 and $69,000.
Use the frequency polygon to identify the class with the greatest, and the class with the least, frequency. (MCAT scores) The scores(x value) are from 10-43. The frequency is from 0-15( y value)
What are the boundaries of the class with the greatest frequency? 29.5-32.5 What are the boundaries of the class with the least frequency? 11.5-14.5
Use the frequency polygon to identify the class with the greatest, and the class with the least, frequency. (MCAT Scores)
What are the boundaries of the class with the greatest frequency? 32.5-35.5 What are the boundaries of the class with the least frequency? 14.5-17.5
Use the frequency histogram to complete the following parts. (a) Determine the number of classes. (b) Estimate the greatest and least frequencies. (c) Determine the class width. (d) Describe any patterns with the data. (Employee Salaries)
(a) There are 7 classes. (b) The least frequency is about 10. The greatest frequency is about 290. (c) The class width is 5. (d) What pattern does the histogram show? About half of the employees' salaries are between $40,000 and $49,000.
