im helpin my lil bro with math and im to high and tired if one of yall can help it would very nice <3 . .Megan wants to know the percentage of students in her class of 35 who are lefthanded. She took three random samples of 7 students each and asked each student, “Are you left or right handed?”. The results are shown below. Explain how she can use her results to make an inference about her class. Sample 1: RRLRRLR Sample 2: LLRLRRL Sample 3: LRLRRRL

🤓 Hello there!

Andrew4289:

hello

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%.
