A study found the following data for the number of intersections in a certain neighborhood:
1 8 6 1 1 5 3 0 0 4
0 0 1 2 1 4 0 4 0 3
1 1 0 1 3 2 4 6 6 0
1 8 3 3 5 0 5 2 3 1
construct a histogram for the data. what proportion of these data points had at least 4 intersections? how many had at most 2 intersections?
Homework Answers
Ans:
Proportion of data had at least 4 intersections=(7+3)/40=10/40=0.25
Proportion of data had at most 2 intersections=19/40=0.475
