Answer:
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.

Answer:
-490
Step-by-step explanation:
= (10+5^2)*((5*-2)+9-3^3)/2
= (10+25)*((5*-2)+9-3^3)/2
= (35)*((5*-2)+9-3^3)/2
= 35*((5*-2)+9-3^3)/2
= 35*((-10)+9-3^3)/2
= 35*(-10+9-3^3)/2
= 35*(-10+9-27)/2
= 35*(-1-27)/2
= 35*(-28)/2
= 35*-28/2
= -980/2
= -490
