Chapter 1, Problem 41(choose chapter or problem)
A sample of n = 10 automobiles was selected, and eachwas subjected to a 5-mph crash test. Denoting a car withno visible damage by S (for success) and a car with suchdamage by F, results were as follows:S S F S S S F F S Sa. What is the value of the sample proportion of successesx/n?b. Replace each S with a 1 and each F with a 0. Thencalculate x for this numerically coded sample. Howdoes x compare to x/n?c. Suppose it is decided to include 15 more cars in theexperiment. How many of these would have to be Ssto give xyn = .80 for the entire sample of 25 cars?
