To calculate the lower quartile,
First arrange from lowest to highest
32, 34, 37, 39, 41, 45, 48, 53, 58 , 60, 61 , 62
Then, we will use the fomula;
1/4 (n+1)
where n=12
The 3rd number is 37
The minimum is the lowest number and is 32
The maximum is the highest number and it is 62
The median is the middle number
45 + 48 / 2 = 93/2 = 46.5
