Question

consider the two - way table.

	group a	group b
category 2	90	84

complete the table below to show the relative frequencies of the data in the first row.
enter numbers in the boxes as decimals to the hundredth place.

	group a	group b

Explanation:

Step1: Find total of first row

First, we need to find the total number of observations in the first row (Category 1). The values for Group A and Group B in Category 1 are 80 and 170 respectively. So the total is $80 + 170 = 250$.

Step2: Calculate relative frequency for Group A

The relative frequency for Group A in Category 1 is the number of observations in Group A (80) divided by the total of the first row (250). So, $\frac{80}{250} = 0.32$.

Step3: Calculate relative frequency for Group B

The relative frequency for Group B in Category 1 is the number of observations in Group B (170) divided by the total of the first row (250). So, $\frac{170}{250} = 0.68$.

Answer:

For Group A in Category 1: 0.32
For Group B in Category 1: 0.68
