Answer:
0.67038
Explanation:
One z-value is negative and the other is positive.
This means we are looking for area between the two given z-values on opposite sides of the mean.
From z-table attached, the area at z = -2.31 is 0.98956
Also, from the second z-table attached, the area at z = 0.47 is 0.68082
But since we are looking for the area between both z-scores, we will now have;
P(-2.31 < x < 0.47) = (0.98956 + 0.68082) - 1
P(-2.31 < x < 0.47) = 0.67038
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.
