The GPAs of 1,000 students at a university have a bell-shaped distribution with a mean of 3.1 and standard deviation 0.25. The GPAs are summarized in the histogram below. We can use the histogram to show how the distribution is approximately symmetric to the mean. Histogram showing university students' GPAs. frequency of GPA on y-axis and GPA on x-axis. Y-axis scaled o to 160 in increments of 20. X-axis scaled 2.2 to 4.0 in increments of 0.2. 2.3 is 1. 2.4 is 2. 2.5 is about 17. 2.6 is about 18. 2.7 is about 43. 2.8 is about 80. 2.9 is about 120. 3.0 is about 145. 3.1 is about 160. 3.2 is about 158. 3.3 is about 118. 3.4 is about 70. 3.5 is about 50. 3.6 is about 18. 3.7 is about 8. 3.9 is about 8. Question 9 Find the approximate percentage of data values that are 0.3 or more from the mean. Enter your answer as a percentage rounded to the nearest whole percent. Hint: The percentage of data values that are 0.3 or more from the mean is the percentage of data values that are 3.4 or more. %
