The U.S. Census Bureau collects information on the racial composition of people in counties throughout the U.S. by asking survey respondents to identify their race. This information allows researchers to estimate the percentage of people in a county who are in various racial categories. The histogram below displays the percentage of adults who identified their race as white in 1,000 counties in the U.S. in 2020. The number above each bar is the frequency of the group of values. The midpoint of each bar is the position on the horizontal axis at the center of the bar. histogram showing 100 counties, frequency of white on y-axis and white on x-axis. y-axis has scale 0 to 500 in increments of 100. x-axis has scale 0 to 100 in increments of 20. 0-10 is 1. 10-20 is 10. 20-30 is 17. 30-40 is 28. 40-50 is 53. 50-60 is 64. 60-70 is 112. 70-80 is 106. 80-90 is 199. 90-100 is 410. Question 2 Using the histogram, estimate the mean. Note: The mean can be estimated by a weighted mean. Enter your answer as a percentage rounded to two decimal places. % I don't know
