One indicator of the health of field mice is the length of their tails. The followingdata on tail length (in mm) were gathered from a representative sample of field micenear Fairfield, Iowa. A biologist would like to construct a 95% confidence intervalfor the population mean tail length of the field mice near Fairfield.
a) Using a graphical display of your choice, display the data in a way that will allowyou to determine whether it would be appropriate to use a t confidence interval toestimate the population mean.
b) Using the graphical display from part (a), would you advise that constructing a tconfidence interval is appropriate?
Explain the basis of your recommendation.
