Question

Can someone please help me with this math question

Answer 1

Explanation:

A). From the table of relative frequencies,

Let the relative frequency of women who prefer mineral water = x

Total of relative frequencies of women preferring purified water and mineral water = 0.59

Since, Total of relative frequencies of women who prefer purified water and mineral water = Relative frequency of women preferring purified water + Relative frequency of women preferring mineral water

0.59 = 0.14 + x

x = 0.59 - 0.14

x = 0.45

B). Relative frequency of men who prefer mineral water = 0.13

Let the frequency of men who prefer mineral water = x

Since, relative frequency =
`\frac{\text{Frequency}}{\text{Total of frequencies}}`

0.13 =
`(x)/(200)`

x = 200 × 0.13

x = 26

Therefore, number of shoppers who are men and prefer mineral water = 26
