Answer 3

Megan can utilize her results from the three samples to get a conception of the percentage of sinistral students in her whole class, which has 35 students. In each sample, she asked 7 students if they were left or dextral.

So, in Sample 1, there were 2 sinistral students. That signifies the proportion of sinistral students in that sample was 2 out of 7, or about 28.6%. In Sample 2, there were 3 sinistral students, making the proportion about 42.9%. And in Sample 3, there were 4 sinistral students, giving a proportion of about 57.1%.

To get an overall estimate of the percentage of sinistral students in her class, Megan takes the average of these proportions. That emerges to be around 42.8%.
