Which data set represents the histogram?

a . {66, 66, 71, 58, 57, 53, 69, 68, 70, 60, 59, 55, 75, 82, 77, 53}
b . {66, 66, 71, 78, 57, 53, 69, 68, 70, 60, 59, 55, 75, 82, 77, 53}
c . {66, 66, 71, 78, 77, 53, 69, 68, 70, 60, 59, 55, 75, 82, 77, 53}
d. {76, 66, 71, 78, 57, 53, 69, 68, 70, 60, 59, 55, 75, 82, 77, 53}

Look at the first bar there are 2 in (50-54)
they can all be possible
a) 53,53
b) 53,53
c) 53,53
d) 53,53
they all have 2 in (50-54)
look at the second bar there are 3 in (55-59)
a,c are not possible
a) 58,57,59,55
b) 57,59,55
c) 59,55
d) 57,59,55
only b and d have 3 in (55-59)
look at the third bar there is 1 in (60-64)
both b and d are possible
b) 60
d) 60
b and d have 1 in (60-64)
look at the fourth bar there is 4 in (65-69)
b is the answer
b) 66,66,69,68
d) 66,69,68
only b has 4 in (65-69)
if you check the rest of the bars with b you will see they are all true
