Steve determined the number of states each of his friends has visited. A number line goes from 0 to 44. The whiskers range from 1 to 40, and the box ranges from 4 to 10. A line divides the box at 8.

Which statement must be true according to the box plot?

The data is skewed left and shows that half of Steve’s friends have visited 4 to 10 states.
The data is skewed left and shows that half of Steve’s friends have visited 10 to 40 states.
The data is skewed right and shows that half of Steve’s friends have visited 4 to 10 states.
The data is skewed right and shows that half of Steve’s friends have visited 10 to 40 states.

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
