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
2.892.642.942.822.762.812.783.082.9 42.86
3.082.822.782.983.002.782.962.903.1 83.16
Intermediate Soil
3.183.383.13.403.383.143.183.262.96 3.02
3.543.363.183.123.862.923.463.443.6 24.26
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.

Monthly water bills for a city have a mean of $108.43 and a standard deviation of $32.09. find the probability that a randomly selected bill will have an amount greater than $155, which the city believes might indicate that someone is wasting water. would a bill that size be considered unusual?
