A sample of n = 10 automobiles was selected, and each was subjected to a 5-mph crash test. Denoting a car with no visible damage by S (for success) and a car with such damage by F, results were as follows:S S F S S S S F S FA) What is the value of the sample proportion of successes x/n?B) Replace each S with a 1 and each F with a 0. Then calculate x for this numerically coded sample. C) Suppose it is decided to include 15 more cars in the experiment. How many of these would have to be S's to give x/n = 0.68 for the entire sample of 25 cars?
