Nancy wants to make a graph to show the relationship between the temperature of water, in degrees Celsius, and the time, in minutes, for which water is heated. She plots the following points: (0, 50), (1, 60), (2, 70), (3, 80), (4, 90)

She uses the following steps to plot the graph:

1. Label origin as (0, 0).
2. On x-axis, label Time in minutes.
3. On y-axis, label Temperature in degrees Celsius.
4. The scale on x-axis starts from 0 and goes up to 5 at intervals of 1.
5. The scale on the y-axis starts from 0 and goes up to 200 at intervals of 50.
Which of the following best describes the graph? (1 point)

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
