3. Spotify tracks the number of songs streamed per day from a sample of 45 people. The data is summarized below. Calculate the mean of the grouped data. Note: you must first find the midpoint of each class. Class Freq 0 to under 2 2 2 to under 4 4 4 to under 6 5 6 to under 8 8 8 to under 10 14 10 to under 12 12
