The following table shows predicted reliability ratings for 16 small cars. (Ratings go from 1 (worst) to 5 (best), with 3 being average.) Predicted Reliability 1 2 st Frequency 4 3 4 5 0 9 2 1 (a) Find the relative frequency distribution for the experiment of choosing a small car at random and determining its predicted reliability. (Enter your answer to four decimal places.) (1) worst (2) (3) average (4) (5) best (b) What is the relative frequency that a randomly selected small car will have a predicted reliability worse (or much worse) than average? (Enter your answer to four decimal places.)
