Answer :
Final answer:
The percentile of a chitauri that weighs 143 lbs is calculated by counting the number of data points below 143, including 143 itself, dividing that by the total number of data points, and multiplying by 100. The percentile indicates where the weight of 143 lbs falls in relation to all chitauri weights.
Explanation:
In this problem, we are trying to find the percentile of a chitauri that weighs 143 lbs. The percentile represents the relative position of a data point in an ordered list of data.
From the problem, we understand that 4 chitauri weigh more than 143 lbs and two weigh exactly 143 lbs. But we do not know the total number of chitauri. Let's suppose the total number is n.
The percentile of a chitauri that weighs 143 lbs is calculated by counting the number of data points below it (including it), dividing that by the total number of data points (n), and multiplying by 100. The positions within the dataset are ranked from less to more, so chitauri that weigh more are not counted.
Therefore, the percentile of a chitauri that weighs 143 lbs is ((2+Number of chitauri that weigh less than 143)/n)*100.
