Match

For each of the following situations, state whether you expect the distributions to be

symmetric, left-skewed or right-skewed.

• Housing prices in a country where 25% of the houses cost below $550,000, 50% of the houses cost below $750,000, 75% of the houses cost below $1,000,000 and there are a meaningful number of houses that cost less than $250,000.

• Housing prices in a country where 25% of the houses cost below $300,000, 50% of the houses cost below $600,000, 75% of the houses cost below $900,000 and very few houses that cost more than $1,200,000.

• Housing prices in a country where 25% of the houses cost below $350,000, 50% of the houses cost below $450,000, 75% of the houses cost below $1,000,000 and there are a meaningful number of houses that cost more than $6,000,000.
