Answer 1

Given,

Age of actress when best award won	Frequency
20-29	29
30-39	36
40-49	14
50-59	2
60-69	4
70-79	1
80-89	2

Thus, we get

Age of actress when best award won	Cumulative frequency
Less than 30	29
Less than 40	29+36
Less than 50	29+36+14
Less than 60	29+36+14+2
Less than 70	29+36+14+2+4
Less than 80	29+36+14+2+4+1
Less than 90	29+36+14+2+4+1+2

Adding up we get

Age of actress when best award won	Cumulative frequency
Less than 30	29
Less than 40	65
Less than 50	79
Less than 60	81
Less than 70	85
Less than 80	86
Less than 90	88
