Let's start with the lower class limits. Lower Class Limit Upper Class Limit Smallest data value = 1.1 Previous class limit + class width = 1.1 + 1.7 = 2.8 Previous class limit + class width = Previous class limit + class width = 6.2 Previous class limit + class width = Now let's find the upper class limits. Lower Class Limit Upper Class Limit Class 2 upper limit - 0.1 = 2.8 Previous upper limit + class width = 4.4 Previous upper limit + class width = 6.2 Previous upper limit + class limit = Previous upper limit + class limit = 9.5
