So first break down the graph into numbers.
Sunday = 4hrs
Monday = 2hrs
Tuesday = 3hrs
Wed = 1 hrs
Thursday = 4hrs
Friday = 0hrs
Saturday = 5hrs
a. To find the total number of hours read in that week you just add up
4+2+3+1+4+0+ 5 = 19hrs total.
b. The mean is calculated by total/number of days
19hrs/7 = 2.714 hrs per day

order the list
0, 1,2, 3, 4,4 , 5,
