I’m sorry, I do not understand the last one.
Step-by-step explanation:
The mean is the average, add all of the values and divide the result by the number of values. The MAD is the mean absolute deviation. You find it by taking the distance between the values and the mean. You then add them together and divide it by the mean. I really hope this helps you!
The sample size suggested by this statement is 664 option second is correct.
<h3>What is the margin of error(MOE)?</h3>
It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:

Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
At 99% confidence Z = 2.576
By using the MOE formula:
0.05 = 2.376×√(0.5(0.5)/n)
After calculating
n = 663.57 ≈ 664
Thus, the sample size suggested by this statement is 664 option second is correct.

Radius / diameter as a length cannot be negative, that's why '-16' is wrong.
Answer:
696.9 cm^3 to the nearest tenth.
Step-by-step explanation:
Radius of the egg = 1/2 * 11 = 5.5 cm.
Volume = 4/3 * pi * 5.5^3
= 696.9099703
