10.1 Here are the weekly wages in a sample of 10 wage and salary workers: 150, 250, 350, 400,

450, 550, 650, 800 , and 1,000.

In small samples like this one, the gaps between the wages are a source of ambiguity in

computing wages at percentiles of the distribution. Let's resolve the median id halfway

between the highest value in the bottom half of the sample and the lowest value in the top

half of the sample. Also, 30 percent of the workers earn $300 or less, but 30 percent also

earn $349.99 or less. To be consistent with the calculation of the median wage, the wage at

30^th percentile is halfway between $300 and $350.

1. Compute the mean and media of wages in this sample.

1. What are the wages at the 10^th and 90^th percentiles in this sample?

1. What is the 90 - 10 percentile ratio? That is, the worker at the 90^th percentile earns________ times as much as the worker at the 10^th percentile.

1. How far from the median wage are the wages at the 1oth and 90^th percentiles? Do wages in this small sample skew to the right?
