Recall that in the second study mentioned (where they later found out that the fish-delivering equipment had been malfunctioning), out of 28 attempts, Buzz pushed the correct button 16 times. Calculate the standardized statistic for these data to investigate whether Buzz’s results provide convincing evidence that his long-run proportion of pushing the correct button is higher than 0.50. Report the calculated standardized statistic and use it to state a conclusion about the strength of evidence.
