This scatterplot shows data on a sample of 20 toddlers observed over several months at a nursery school. Can you predict how many calories a child consumes based on how long they remain at the lunch table? “Time” is the average number of minutes a child spent at a table when lunch was served. “Calories” is the average number of calories consumed by the child during lunch. The least squares regression equation is: calories = 560.65125 – 3.0770733 × time....

L. Collect data from several fast food chains on the number of fat calories and grams of saturated fat in menu items. Record at least 12 ordered pairs of (fat calories, grams of saturated fat) Organize your data in a table. Il. Make a scatter plot of the data on graph paper. Be sure to label the axes and use an appropriate title for the graph. You may wish to use a graphing calculator, spread sheet, or other technology resource...

A dietician wanted to find out if there was any association between the amount of calories (Calories; measured in calories) and the total fat (Fat, measured in grams per serving) among chicken sandwiches made from different fast food chains like McDonald’s, Wendy’s etc. A sample of 20 chicken sandwiches was collected and the information was recorded. The data set “S1181 HW2 Q4 Data.xlsx” is available on D2L. Note: Use the variable Fat as the Y-variable and the Calories as the...

The table below gives data from a study that shows that social exclusion causes "real pain." That is, activity in the area of the brain that responds to physical pain goes up as distress from social exclusion goes up. The scatterplot for this data shows a moderately strong linear relationship. The data are given below.
