Answer :

We need to find the mean and the standard deviation of the data.

mean: 66,4

standard deviation: 5,6

Now we add and subtract the sd from the mean, that would give you an interval

60.8

72.

Now we count the numbers (data) that are within that interval and divide it by the total number of data

77.8%
