Refer to Data Set 14 in Appendix B and use the 21 braking distances (ft). Are there any outliers? Is there strong evidence suggesting that the data are not from a population having a normal distribution?
Pareto Charts. In Exercises 15 and 16, construct the Pareto chart.

gas (GHG) emissions from the sample of cars. Does the configuration of the points appear to suggest that the amounts are from a population with a normal distribution? Why or why not? Stemplots. In Exercises 13 and 14, construct the stemplot.

Use data from the graph of the temperature T(t) in the following figure to estimate the constants T m , T 0 , and k in a model of the form of a first-order initial-value problem: dT/dt = k(T T m ), T(0) = T 0 .
