Answer 1

Solution:-

a) The state with the highest amount of colleges and Universities fall within range of 1200 to 1400 Universities.

b) 0 to 200 number of Universities are most common for a state.

c) 5 states have at-least 400 Universities.

d) The proportion of states that have at-least 400 Universities = 0.10

The number of states have at-least 400 Universities = 5

Total number of states = 37 + 8 + 3 + 1 + 1 = 50

The proportion of states that have at-least 400 Universities = 5/50

The proportion of states that have at-least 400 Universities = 0.10

e) The proportion of states that have at-most 200 Universities = 0.74

The number of states have at-most 200 Universities = 37

Total number of states = 37 + 8 + 3 + 1 + 1 = 50

The proportion of states that have at-most 200 Universities = 37/50

The proportion of states that have at-most 200 Universities = 0.74
