30 random samples of high school students were asked if they played a sport for their high school. Each sample was 20 students.
The dot plot represents the 30 random sample proportions.
Choose ALL that are correct.
A) A sample proportion of 0.20 means that 4 of 20 high school students responded that they play a sport.
B) Based on the sample distribution, the best prediction for the proportion of all high school students that play a sport is 0.10.
C) The mean of the 30 sample proportions calculated to the nearest hundredth is 0.16.
D) The shape of the sample distribution is fairly symmetrical.

Step-by-step explanation:
Sine uses the ratio, so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.
You can't reduce this any further because there is an unknown variable.
