Answer 2

Answer:

(a) 50; (b) 64; (c) 36

Step-by-step explanation:

(a) The range is (largest value) - (smallest value) = 80 - 30 = 50.

(b) The value of the median is the value of the middle term, after the terms have been arranged in increasing order.  When given a graph like this one, you can spot the median easily:  It's the x-value of the vertical line inside the box:  64.

(c) Look at the x-values of the two box endpoints:  38 and 74.  Subtract the larger from the smaller:  74 - 38.  This gives us the IQR:  74 - 38 = 36.
