Lab Assignment Name: Section 2.1 and 2.2 Due Date: Math 34 This Lab is to be worked in the Math Lab when an instructor is present. You may work with your classmates, but be sure to complete your own assignment to turn in. To receive credit for this assignment you must log in at least 2 hours each week. In Exercises 5-10, identify the class width, class midpoints, and class boundaries for the given frequency distribution. The frequency distributions are based on real data from Appendix B. 6.

In Exercises 5-8, answer the questions by referring to the following Minitab-generated histogram, which depicts the weights (grams) of all quarters listed in Data Set 29 "Coin Weights" in Appendix B. (Grams are actually units of mass and the values shown on the horizontal scale are rounded.) 20- 15 Frequency 10 5. 5. 6 5.7 5.8 5.9 6.0 6.1 6.2 6.3 Weights of Quarters (grams) 5. Sample Size What is the approximate number of quarters depicted in the three bars farthest to the left? 6. Class Width and Class Limits Give the approximate values of the class width, and the lower and upper class limits of the class depicted in the bar farthest to the left. PAGE 18Constructing Frequency Dietrlbutlone. In Exercises 11-18, use the indicated data to construct the frequency distribution. (The data for Exercises 1316 can be downloaded a! THolaSIats.com.) 11. Old Faithful Listed below are sorted duration times (seconds) of eruptions of the Old Faithful geyser in Yellowstone National Park. Use these times to construct a frequency distribu- tion. Use a class Width of 25 seconds and begin with a lower class limit of 125 seconds.

Diastolic Blood Pressure Refer to the data listed in Exercise 6. Identify the two values that are closest to the middle when the data are sorted in order from lowest to highest. (These values are often used to find the median, which is defined in Section 3-1.) In Exercise 15, construct a pie chart and a pareto (bar) chart. 15. Awful Sounds In a survey, 1004 adults were asked to identify the most frustrating sound that they hear in a day. In response 279 chose jackhammers, 388 chose car alarms, 128 chose barking dogs, and 209 chose crying babies (based on data from Kelton Research). Section 2.4: Construct a scatterplot: 8.

Scatterplot What is a scattcrplot? What type of data is required for a scatterplot? What characteristic of the data can be better understood by looking at a scatterplot? In exercises 5 and 6, Construct the stemplot: 5. Pulse Rates Listed below are pulse rates (beats per minute) of females selected from Data Set 1 \"Body Data\" in Appendix B. All of those pulse rates are even numbers. Is there a pulse rate that appears to be an outlier? What is its value? 8094586656827886885636663476786466786064 6.
