The "Even More Music" worksheet in the data pack represents a sample of hit songs (released in the 1980's, 1990's, 2000ʻs, and 2010's) and their length (measured in minutes). Using a 5% significance level, conduct an appropriate hypothesis test to determine whether the average length of a song differs by decade. Calculate the test statistic for this hypothesis test.
