MATH 1342/NCBM 0142 Elementary Statistics with Support Distance Learning Distance Learning Activity Unit 1B: Proportions and Histograms Proportions from a two-way table: The whole and the part Proportion of (whole) that who (part) Look for the word "of" to find the whole. Once identified, only use that row or column. 1. Find the proportion of those with several or a few large tattoos who are in favor (Yes) of legalization, to two decimal places. In favor of legalization? Yes Not sure No Total My body is covered in them 1 0 1 Several, or a few large 3 0 1 4 Any tattoos? One or two, small 6 1 3 10 None 10 7 19 Total 20 11 34 2. Find the percent of those in favor (Yes) of legalization have several or a few large tattoos? Round a decimal answer to three places before converting to percent. Use correct notation. In favor of legalization? Yes Not sure No Total My body is covered in them 1 0 1 Several, or a few large 3 1 4 Any tattoos? One or two, small 6 1 3 10 None 10 2 7 19 Total 20 3 11 34 3. The following proportions are calculated from the tables above. Part a. Sample proportions follow the model p =- For the proportion p= - =0.333, consider which of these could Whole possibly be the whole. Not sure about legalization With one or two small tattoos b. And which of these could possibly be the part? O Not sure about legalization With one or two small tattoos Circle whole or part for each description, based on your answers above. p= =0.333 Circle one for each: Not sure about legalization (whole / part) With one or two small tattoos (whole / part) d. Follow this same process to identify the whole and the part for each proportion given below. p= - 7 19 -=0.368 Circle one for each: No, not in favor of legalization (whole / part) None, with no tattoos (whole / part) Page 1 of 3
