Question

Cristina asked $150$ people the amount of water they drink in one day. The grouped frequency table for the amount of water people drink in one day is given below:

people drank less than $0.5$ liters of water a day and people drank between $1.5$ liters and $2.5$ liters a day.

Answer 1

From the frequency table, we can see that $5$ people drank less than $0.5$ liters of water a day.

$50$ people drank greater than or equal to $1.5$ liters and less than $2$ liters water a day.
$23$ people drank greater than or equal to $2$ liters and less than $2.5$ liters water a day.

$\therefore 50+23=73$ people drank between $1.5$ liters and $2.5$ liters water a day.
