Answer:

x × 0.1 < y × 0.2

x = 100, y = 10

Step-by-step explanation:

10% of a really large number can be bigger than 20% of a small number. 10% of 100 is 10. 20% of 10 is 2. 10 is bigger than 2 so Sergi's claim is false.

Crank

How do you compare two-way frequencies in a relative frequency table
Nikolay [14]
  • To avoid such problems when comparing the categorical variables in a two-way frequency table, we need to exam the table by separate categories (rows or columns). When a relative frequency is determined based upon a row or column, it is called a "conditional" relative frequency.
  • Two-way relative frequency tables show what percent of data points fit in each category. ...
  • For example, here's how we would make column relative frequencies:
  • Step 1: Find the totals for each column.
  • Step 2: Divide each cell count by its column total and convert to a percentage.
