The better statistics which can be used to compare the given distributions are mean and standard deviation.
<h3>What is a z-core?</h3>
A z-core is also referred to as a standard score and it can be defined as a statistical measure of the distance between a data point (raw score) and the mean, especially when standard deviation units are used.
In Mathematics, z-scores can either be negative or positive and it is generally calculated by using this formula:
![Z=\frac{x\;-\;u}{\delta}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx%5C%3B-%5C%3Bu%7D%7B%5Cdelta%7D)
<u>Where:</u>
- x is the observed data or sample mean.
is the standard deviation.
In conclusion, the better statistics which can be used to compare the given distributions are mean and standard deviation.

Answer:
Descriptive
Step-by-step explanation:
Descriptive statistics uses the data that helps to analyse, describe, and elaborate data accurately. It also provides information regarding the population through graphs or tables. Four types of descriptive statistics are measures of frequency, measures of central tendency, measures of dispersion, and measures of position.
The given example in question is <u>descriptive statistics</u>.
Step-by-step explanation:
It will take 5 years because when you add 5 to Stephanie's age = 18 + 5 = 23
And Ashley age = 64 + 5 = 69
So when you multiply 23 by 3 = 69
This means after 5 years Ashley will be 3 times as old as Stephanie
