Question

like skinny jeans (sample 20 each)
a: boys
b: girls
note: 20 samples of 20 students each
about how far apart are the means in terms of the girls variability?
½ x mad
1 x mad
2 x mad
3 x mad

Explanation:

Step1: Find the difference between the means

The mean for boys is \(5.4\) and for girls is \(7.2\).
\(7.2 - 5.4=1.8\)

Step2: Divide the difference by the girls' MAD

The girls' MAD is \(1.0\).
\(\frac{1.8}{1.0} = 1.8\approx2\)

Answer:

\(2\times\text{MAD}\)
