The first and third quartiles were calculated incorrectly. Also, this means the inter quartile range is incorrect.

Step-by-step explanation:

The first quartile is going to be the median of the lower half of the data set {89, 93, 99, 110}  this median is (93+99)/2, or 96.

The third quartile can be calculated the same way with the data set {135, 144, 152, 159} This gives us 148 as the third quartile.

Lastly, the interquartile range is just the difference between the first and third quartiles, which is 52.
