Explanation:

Step1: Sum all the number of songs

First, we list out the number of songs for each album: 14, 13, 14, 14, 14, 14, 17, 30, 14, 13.
Now we sum them up: \(14 + 13 + 14 + 14 + 14 + 14 + 17 + 30 + 14 + 13\)
Let's calculate step by step:
\(14+13 = 27\)
\(27+14 = 41\)
\(41+14 = 55\)
\(55+14 = 69\)
\(69+14 = 83\)
\(83+17 = 100\)
\(100+30 = 130\)
\(130+14 = 144\)
\(144+13 = 157\)

Step2: Calculate the mean

The mean is the sum of the data divided by the number of data points. There are 10 albums, so the mean \(\bar{x}=\frac{\text{Sum of data}}{\text{Number of data points}}=\frac{157}{10} = 15.7\)

Answer:

15.7
