Question
2.3 - Convert the vertical axis to relative frequency and show the value that would replace each of the values on the vertical axis
dorplot of the glucose readings fr 132 people (from NHANES) is shown. Some doctors recommend that glucose readings not be above 120 mg/dl. a. How many of these people have glucose readings above 120 mg/dl? b. What percentage of these people have glucose readings above 120 mg/dl? 40 100 120 140 160 180 200 Glucose (mg/dl) 2.3 Pulse Rates The histogram shown is for pulse rates for 125 people. Convert the vertical axis to relative frequency and show the value that would replace each of the values on the vertical axis. (Source: NHANES) Frequency 25 20- 15- 10- 5 0 50 Expan 60 70 80 90 100 110 120 Pulse Rate (beats per minute) 2.4 Fast Food Calories The histogram shown is for number of calories in a sample of fast-food items. (Source: StatCrunch survey). a. What is the bin width of the histogram? b. Would this graph be best described as unimodal or bimodal? c. Approximately what percentage of the fast-food items contained fewer than 300 calories? 0.21
