### Interpreting Frequency Tables

#### Practice 2

The table below shows the number of men and women who went to the hospital in the month of May.

a) On which day were the number of men who went to the hospital the highest?
b) On which day were the number of women who went to the hospital the lowest?
c) How many men visited the hospital on Monday, Tuesday, and Wednesday?
d) How many women visited the hospital from Monday to Sunday?
e) How many people went to the hospital on Friday, Saturday, and Sunday?

a) On which day were the number of men who went to the hospital the highest?
Friday. 28 Men went to the hospital that day.

b) On which day were the number of women who went to the hospital the lowest?
Saturday. 12 women went to the hospital on Saturday.

c) How many men visited the hospital on Monday, Tuesday, and Wednesday?
Monday: 20
Tuesday: 26
Wednesday: 21
Hence; 20 + 26 + 21 = 67 men

d) How many women visited the hospital from Monday to Sunday?
Monday: 17
Tuesday: 19
Wednesday: 29
Thursday: 23
Friday: 20
Saturday: 12
Sunday: 19
Hence; 17 + 19 + 29 + 23 + 20 + 12 + 19 = 139 women

e) How many people went to the hospital on Friday, Saturday, and Sunday?
Men
Friday: 28
Saturday: 22
Sunday: 14
Total = 28 + 22 + 14 = 64
Women
Friday: 20
Saturday: 12
Sunday: 19
Total = 20 + 12 + 19 = 51
Total People: 64 + 51 = 115 Men and Women
