Answer:
I would say that it is all of them besides the 35% of the participants do not like to surf.
The correct statements are:
A)
The total number of students who were studied= 160
Number of boys= 105
Hence, Percentage of boys is calculated as:
[tex]Percent\ Boys=\dfrac{105}{160}\times 100\\\\i.e.\\\\Percent\ Boys=\dfrac{1050}{16}\\\\\\Percent\ Boys=65.625\\\\which\ is\ approximately\ equal\ to:\\\\Percent\ Boys=66\%[/tex]
B)
Number of students who like to surf=125
Hence,
Percent who like to surf is calculated as:
[tex]=\dfrac{125}{160}\times 100\\\\\\=\dfrac{1250}{16}\\\\=78.125\%[/tex]
C)
Number of boys=105
and number of boys who like to surf=80
Hence, the proportion of boys who like to surf is:
80/105
D)
Number of people who do not like to surf=35
Number of girls who do not like to surf=10
Hence,the proportion of girls who do not like to surf is:
10/35
E)
Proportion of boys who like to surf=80/105=0.76190
and proportion of boys who like to surf= 45/55=0.8181
Hence, the proportion of girls who like to surf are more than those of boys who like to surf.
( Since, 0.8181 < 0.76190 )
