Question

A sports psychologist performed a study of some visualization techniques that she developed to improve athletic performance. She used amateur golfers and amateur tennis players as participants. In her study, 50% of the participants were golfers, and the other were 50% tennis players. (No participant was both a golfer and a tennis player.) The visualization techniques seemed quite helpful for both the golfers and the tennis players: 80% of the golfers reported a solid improvement in their performance after using the visualization techniques, and 70% of the tennis players reported a solid improvement in their performance after using the techniques.

Explanation / Answer

What is the probability that a randomly chosen participant did not report a solid improvement in performance after using the visualization techniques

P( I / G) = 0.5 / 0.7 = 0.7143

What is the probability that a randomly chosen participant did not report a solid improvement in performance after using the visualization techniques

P( I / G) = 0.5 / 0.7 = 0.7143
