The main mathematical component will be the chi-square goodness-of-fit test. see attachment.

Since it is lengthy to identify the songs by name so I am referring them by numbers.
For my experiment I got the following outcome,
Song
Number
1 2 3 4 5 6 7 8 9 10
No of
times it
played
7 6 4 6 5 5 2 7 3 5
Hypothesis: Here we are interested to check whether the shuffling of song is random or not. This is
equivalent in saying,
H0: The numbers are random against H1: they are not.
Test Statistic and condition: Testing the above hypothesis can be done by using the chi-square goodness
of fit test which is given as,
X2 =
( )
