Question

Formula to calculate mean for frequency distribution

Answer 1

✍️$\huge\bf\red{Answer}$✍️

If we multiply each midpoint by its frequency, and then divide by the total number of values in the frequency distribution, we have an estimate of the mean. Estimate the mean for this set of data. The sum of the product of the midpoints and frequencies is 1005. (Just add the values in the last column).
