A sample of 50 plastic toggle levers with a nominal thickness of 1.95mm were measured and recorded the following actual thickness measurements in mm. 1.89 1.94 1.91 1.72 1.89 1.99 1.92 1.88 2.03 1.79 1.66 1.88 1.93 1.87 2.23 1.85 2.25 1.91 1.89 2.29 1.94 2.06 2.04 1.99 2.05 1.99 2.13 1.84 1.94 2.03 1.85 2.07 2.03 1.99 1.97 2.17 2.18 2.04 1.87 1.91 1.92 1.97 1.78 1.97 1.95 1.84 2.01 2.06 1.8 2.02 By drawing a cumulative frequency chart or otherwise, calculate percentage of levers that don't have more than the nominal thickness. 51 %
