The fourth column is labeled total with entries 300, 100, 400. Which is the marginal relative frequency for the people who do not like bar soap? StartFraction 100 Over 400 EndFraction StartFraction 120 Over 400 EndFraction StartFraction 280 Over 400 EndFraction StartFraction 300 Over 400 EndFraction

Answer 1

Answer: 100/400

Step-by-step explanation:

$\begin{array}{l|c|c|c}&Liquid&Not\ Liquid&Total\\ Bar&200&100&300\\Not\ Bar&80&20&100\\Total&280&120&400\end{array}$

$\dfrac{Not\ Bar:Total}{Total:Total}\quad =\dfrac{100}{400}$
