1.3 Exercise 2 — Statistics

the table shows the amount, in inches, of annual rainfall in a sample of towns.

Rainfall (Inches)	Frequency	Relative Frequency	Cumulative Relative Frequency
2.95–4.97	6	$\frac{6}{50}$ = .12	.12
4.97–6.99	7	$\frac{7}{50}$ = .14	.12 + .14 = .26
6.99–9.01	15	$\frac{15}{50}$ = .30	.26 + .30 = .56
9.01–11.03	8	$\frac{8}{50}$ = .16	.56 + .16 = .72
11.03–13.05	9	$\frac{9}{50}$ = .18	.72 + .18 = .90
13.05–15.07	5	$\frac{5}{50}$ = .10	.90 + .10 = 1.00
	Total = 50	Total = 1.00

From the table, find the percentage of rainfall that is less than 9.01 inches.
