Question

Please help and explain how you got the answer I'm really bad at these

Answer 1

The range of the data is C. 160 because the biggest number, 280, subtracted by the smallest number, 120, is equal to 160.

Answer 2

Here, Median of Q1 = 140+150/2 = 290/2 = 145
Median of Q3 = 226+245/2 = 471/2 = 235.5

Now, Interquartile range = 235.5 - 145 = 90.5

In short, Your Answer would be Option B

Hope this helps!
