Suppose 250 randomly selected people are surveyed to determine whether or not they play a musical instrument. The sample proportion of successes is determined to be p' = 0.86 and the sample proportion of failures is q' = 0.14 What is the 95% confidence interval for the proportion of the population who play a musical instrument? Z0.10 Z0.05 Z0.025 Z0.01 Z0.005 1.282 1.645 1.960 2.326 2.576 Use the table of common z-scores above. • Round the final answer to three decimal places.
