Minutes Doing Aerobics vs. Number of Calories Burned Minutes doing aerobics Number of calories burned 3 14 4 21 6 28 10 47 15 78 24 125 Using a regression calculator, she got a regression line of y almost-equals 0.19 x + 0.49. What did she do wrong? A calculator screen. A 2-column table with 6 rows titled Data. Column 1 is labeled x with entries 14, 21, 28, 47, 78, 125. Column 2 is labeled y with entries 3, 4, 6, 10, 15, 24. A 2-column table has 6 rows. Column 1 is labeled x with entries 14, 21, 28, 47, 78, 125.
