Answer:
30%
Step-by-step explanation:
In this question, we are to calculate the percentage of students who are female and do not play instruments.
We can first infer this from the table;
The number of females who do not play instruments = 64
The percentage of females who do not play instruments = number of females who do not play instruments/total number of students surveyed * 100%
That will be;
64/213 * 100% = 30.04 which is approximately 30%
Given the two way frequency table
<span> Sunny Snowy Total
Male 17 11 28
Female 15 16</span> 31
Total 32 27 59
To obtain the relative frequency table for the above data, we divide each cell of the table by 59 (the overall total).
Therefore, the relative frequency table is given below:
<span> Sunny Snowy Total
Male 0.288 0.186 0.475
Female 0.254 0.271</span> 0.525
Total 0.542 0.458 1
