Biology 280; Spring 2019 Homework 1a 1.3) Children's food choices. (Page 13) Do popular cartoon characters on food packages influence children's food choices? A study asked 40 young children (ages four to six) to taste graham crackers presented in a package either with or without a popular cartoon character, and to indicate whether the two foods tasted the same or one tasted better. Unknown to the children, the crackers were the same both times. Here are the findings. Number of Children Taste Preference Without character Taste the same With character Percent 7.5 37.5 15 55.0 Present these data in a well-labeled bar graph. Would it also be correct to make a pie chart? What do the data suggest about the influence of cartoon characters on graham cracker preference in young children? 1.5) Healing of Skin Wounds. (Page 16) Biologists studying the healing of skin wounds measured the rate at which new cells closed a razor cut made in the skin of an anesthetized newt. Here are the sorted data from 18 newts, measured in micrometers (millionths of a meter) per hour. 11 12 14 18 22 22 23 23 26 27 28 29 30 33 34 35 35 40 Make a histogram of the healing rates using classes of width 5 micrometers/hour starting at 10 micrometers/hour. (Make this histogram by hand even if you have software, to be sure you understand the process. You may want to compare your histogram with your software's choice.) 1.24) Eating Habits. (Page 32) You are preparing to study the eating habits of elementary school children. Describe two categorical variables and two quantitative variables that you might record for each child. Give the units of measurements for the quantitative variables.
