i can do that.

Answer 7

Having seen that the values range from 1 to 29 you need to choose a Class Interval.
A suitable choice would be 5 giving 0 to 5, 6 to 10, 11 to 15, 16 to 20, 21 to 25, and 26 to 30 for the widths of each bar of the histogram.

Answer 8

The data values for the first bar of the histogram are 1, 2, 2, 3, 4, giving a total of 5 values.

Answer 9

Can you now find the number of values for each of the remaining bars and plot them?
