ITS ON A TEST Claim: Fleas can jump an unusually far distance for their size. If a person could jump as far as a flea, they could reach Lady Liberty's Torch
Information: The average flea is 1 mm in length, and it can jump 13 inches. 1 mm =
0.0394 in, and 1 foot = 12 inches. The height of the Statue of Liberty is 305 feet tall.
Questions: Leah is 5 feet and 4 inches tall.
(a) How far would Leah be able to jump if her proportional jump distance were the
same as a flea's?
(b) is the original claim true or false? Justify your reasoning.

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
