• 21/25 = 0.84 or about 84% of the games

• 4/25 = 0.16 or about 16% of the games

• 25/21 = 1.19 or 1.19% of the games

• 25/4 = 6.25 or 6.25% of the games

The following parallel dotplots show the total family income of randomly chosen individuals from Indiana (38 individuals) and New Jersey (44 individuals). Which of the following correctly compares the shape of the distribution?

• The Indiana distribution is roughly symmetric, while the New Jersey distribution is right-skewed.

• The distribution for Indiana has a similar center to the distribution for New Jersey, around $45,000.

• The variability for Indiana is less than the variability for New Jersey.

• $160,000 appears to be an outlier for the Indiana distribution and there isn't any obvious outliers for the New Jersey distribution.
