Atomic radii INCREASES when going DOWN a group because of more energy levels and DECREASES going ACROSS a group because of the increasing positive charge of the nucleus pulling in on the electrons.
The option that is an accurate statement about Sample Size is; A: A larger sample size is needed for increased accuracy.
<h3>What is true about Sample Size?</h3>
Sample size determination is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample.
Now, the smaller the sample size, the lesser the accuracy as you have possibility of biased research from just a handful of people. However, the larger the sample, the greater the degree of accuracy of the research.
Thus, we can say that the option that is an accurate statement about Sample Size is; A: A larger sample size is needed for increased accuracy.
Complete question is;
Which of the following is an accurate statement about sample size?
Select one:
a. A larger sample size is needed for increased accuracy.
b. A smaller sample size will reduce the size of the confidence interval.
c. Sample size is a constant percentage of the population size.
d. Sample size is independent of the confidence interval.

The displacement of the girl which the relative change in her position from her starting point. Therefore, the shortest distance between her initial and final position is 58.85 m North - West
From the sketch of the girls movement attached below, the displacement of the girl can be calculated thus :
Using Pythagoras :
Displacement, d = √(50² + 20²)
d = √(2500 + 400)
d = √2900
d = 53.851
Therefore, the displacement of the girl, which is the shortest distance between her current position and starting position is 53.85 meters NW.
