The mean of the data is 45 and the standard deviation is 20. Can anyone help me please?

10 20 30 40 50 60 70 80 90 100 110 1. If we want to estimate the probabilities of this graph, we should use Chebyshev's Theorem 2. How much of the data can we estimate to be between x- values -15 and 105? Round to the nearest tenth. There is at least of the data is between -15 and 105. 3. How much data is between 2 standard deviations of the mean? There is at least % of the data between 2 standard deviation of the mean
