3rd Quartile of the data is 64 people.
The given set of data is 1 1 1 7 10 13 14 16 18 19 19 22 25 28 31 40 45 46 50 55 56 57 58 59 61 61 64 64 76 91 95 98 98 99 99 100 .
The data represents the number of people visited an art gallery during its first 36 hours of opening.
Since we have to find the 3rd quartile we divide 36 hours into 4 equal parts, each of 9 hours.
The 1st quartile will be 36/4 = 9 hours.
Second quartile will be 9 x 2 = 18 hours.
Third quartile will be 9 x 4 = 27 hours.
Thus to find the 3rd quartile of the data set, we need to find the number of people visited the art gallery in 27 hours.
We can see that the number of people visited in the first 27 hours is 64 people.
Therefore, 3rd Quartile = 64 people.
