Olli's company wanted to find out the consumption habits of its customer base with a survey. Olli had at his disposal the attached Excel table (below), which showed the entire customer's household separated by age group and gender. Each box contains the number of customers who belong to a certain age, gender, and size group. Olli wanted to survey 400 respondents. How many answers should Olli receive from the following customer groups so that the sample corresponds as closely as possible to the distribution of customers by age, gender, and household size (round any decimal value according to normal rounding rules)? Always assume a uniform distribution within a class.

1. women under 26 in all households?

2. people over 30 living in a two-person household, regardless of gender?

3. men aged 19-35 living in a household of less than three people?
