Answer:
The percentage of scores higher than 72 is 99.85%
Explanation:
The empirical rule states that about 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)
We can use the relationship below
255-σ(61)=72
61σ=255-72
61σ=183
σ=3
The area is as shaded below
The percentage of scores higher than 72 is 99.7%+0.15%=99.85%
Based upon the given case, the 6 pounds 1 ounce is taken as Lower Quartile. Thus, option C is correct.
<h3>What are quartiles?</h3>
The quartiles can be understood as the division of the numbers or data into group of four or less or more, but in equal quartile size.
Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.
Therefore, for 6 pounds, 1 ounce the correct option is C.
