elle measured the height of a plant, in inches, every week for four weeks after planting it. the table shows her data.

look at the image for the data

the height of the plant, h , in inches , can be modeled by the function h (t) = 1.5t + 3, where team represents the time in weeks.
based on this model, what is the best prediction for the height of the plant after 12 weeks?

a 16.5 inches

b 21 inches

c 22.5 inches

d 27.3 inches

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
