The product of the frequency and PlayCount gives the number of songs
played from the information in the histogram.
Correct responses (rounded to the nearest whole integer)
1. 2%
2. 27 PlayCount per song
3. 68%
<h3>How does one analyze an histogram?</h3>1. The given data from the histogram is presented in a tabular form as follows;
The percentages of song that where played over 100 times is given as follows;
∑f = 899+224+126+96+71+52+39+41+44+23+14+12+3+4+3 = 1651
Number of songs played over 100 times = 14 + 12 + 3 + 4 + 3 = 36
2. Mean of a frequency distribution is given as follows;
Where;
x = The PlayCount
From MS Excel, we have;
∑f·x = 44410
Which gives;
3. Number of songs played less than 20 times = 899 + 224 = 1,123
