Using the proportion concept, it is found that:
- According to Tyler's sample, the estimate is of 0.2 = 20%.
- According to Kyran's sample, the estimate is of 0.17 = 17%.
- Due to the higher sample size, Kyran's estimate is more accurate.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and larger sample sizes lead to more accurate predictions.
In Tyler's sample, 2 out of 10 students would dye their hair blue, hence:
p = 2/10 = 0.2.
In Kiran's sample, 17 out of 100 would, hence:
p = 17/100 = 0.17.
Due to the higher sample size, as 100 > 20, Kyran's estimate is more accurate.
