In 2007, the median age of U.S. residents was 36.6 years, as reported by the U.S. Census Bureau in Current Population Reports. A random sample of 10 U.S. residents taken this year yielded the following ages, in years.

At the 1% significance level, do the data provide sufficient evidence to conclude that the median age of today€™s U.S. residents has increased from the 2007 median age of 36.6 years?

Use the Wilcoxon signed-rank test to perform the required hypothesis test.
