The Met Several years ago the Metropolitan Opera in New York City began live-to-cinema opera transmissions in an effort to attract a greater audience. The broadcasts are now seen in 64 countries, and according to the new general manager, the Met is reaching younger people.37 A random sample of people who attended a performance at the Metropolitan Opera was obtained and the age (in years) of each was recorded. The data are given in the following table.
Assume the underlying distribution of ages is continuous. Use the Wilcoxon signed-rank test with a = 0.05 to determine whether there is any evidence that the median age of those attending a performance is less than 65 years. Find the p value for this test.
