<h2>Answer with explanation:</h2>
We are given a two-way table that represents the frequency of three types of music.
Hence, the relative frequency table is given by:
Female Male Total
Country 145/1015 106/1015 251/1015
Rap 158/1015 240/1015 398/1015
Rock 214/1015 152/1015 366/1015
Total 517/1015 498/1015 1015/1015
Female Male Total
Country 0.143 0.104 0.247
Rap 0.155 0.237 0.392
Rock 0.211 0.150 0.361
Total 0.509 0.491 1
Hence, clearly we could see that the relative frequency of the music country is much low as compared to that of Rock and rap.
Hence, there is a much difference between the bar of Country as compared to Rock and rap.
and there is a low difference between the bar of rock and rap.

Step-by-step explanation:
Given
Required
Determine the type of solution
From the matrix, we have:
3 non-zero rows and 5 variables (the last column is the result)
When the number of variables is more than the number of non-zero rows, then such system has infinitely many solutions
i.e.
