ences in your response. Investigation 2: Songs from Spotify - Mode and Popularity A random sample of 3439 songs was selected from the Spotify database and twelve variables were measured for each song. Remember, the Mode variable indicates the type of scale the song's melodic content is derived from (Major or Minor). Popularity is on a scale of 0 to 100 and songs with higher numbers are more popular. Let us now investigate whether Major songs are significantly more "Popular" than Minor songs. Let us define "Popular" as songs that earned a popularity rating of 50 or higher. From the random sample of songs, there were 1964 Major songs and of those 853 were rated "Popular." In addition, there were 1475 Minor songs and of those 587 were rated "Popular." In this invesligation we will subtract (Major - Minor). a) Define the population parameter using context and symbols in one complete sentence. b) State the hypotheses using the claim. c) Check the specific conditions necessary to consider…
