To find the mean, we need to add up all the values and divide by the total number of values. Adding up all the values in the table, we get: 1+1+1+1+2+2+2+2+2+2+2 = 18. There are 11 values in the data set, so dividing the sum by 11, we get 18/11 = 1.63. Rounded to two decimal places, this is 1.64, which is closest to choice B, 2.15. Therefore, the best choice is B.
