8. Identifying different data sets with tables - 2 Suppose your friend Shen made a New Year's resolution to lose weight and has asked you for help. You begin by tracking his weight the first seven weeks in the new year and record his weight at the beginning of each week, along with other variables of interest. The data you collect are displayed in the following table. (Note: You can drag and position this table throughout the problem by clicking the blue push pin icon and then dragging the table to the desired location.) obsno date: period height weight calories sleephrs weekday Monday 1 Jan. 11 1 185 2,200 8 Jan. 8 2 2 182 Monday 3 2,100 3 6 180 2,000 Jan. 15 3 Monday 4 9 Jan, 22 2,500 4 179 Monday 174 2,400 4 Monday 5 5 Jan. 29 7 3,400 176 Monday 6 6 Feb. 5 3,000 10 Monday 180 7 Feb. 12 7 RRRRRRR 70 70 70 70 70 70 70 obsno observation number date date data were collected period date index equal to 1 on first date, 2 on second date, and so on height height in inches M7 weight weight in pounds calories calories consumed on that date sleephrs -hours slept that night data set, with a data frequency. The data in the table are an example of a True or False: When performing econometric analysis on this type of data, it does not matter whether or not the data are sorted by chronological order. True O False Use the data in the table to plot all seven combinations of periods and weights on the following graph by dragging the purple diamond symbol. The horizontal axis represents the date index, equal to 1 on first date, 2 on second date, and so on, while the vertical axis represents the individual's weight in pounds. (Note: You can drag and position the table throughout the problem by clicking the blue push pin icon and then dragging the table to the desired location.) 100 100 Weight 100 102 100 176 170 174 WEIGHT (Pounds) D Use the previous table and graph to answer the following question.
