What percent of the data points will fall in that range? Answer: percent (Enter a number between 0 and 100, not 0 and 1 and round to 2 decimal places) Question Help: 8 Message instructor Submit Question 11:44 Done myopenmath.com AA Chapters 6.1 - 6.2 Homework Score: 0/21 0/21 answered Progress saved Done VOCO . . .
