Use the following sample data set 2.1, 2.8, 3.7, 4.1, 4.6, 5.8, 6.3, 7.4, 8.2, 8.5, 9.6, 10.1, 10.3, 10.9, 11.0, 11.8, 12.4, 13.6, 13.9, 14.3, 14.6, 15.5,
15.9, 16.7, 16.9
The frequency for the second class is
3
5
6

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
