Step-by-step explanation:
Learning could be explained as a process of acquiring knowledge about a certain subject, trade or other aspects of life. In terms of learning about certain school subjects, a student needs to discover him or herself in other to make acquiring knowledge easy and less tedious for him or her. Now, there are designated tools more than evwr which could aid learning. A very important recommendation which could aid acquiring matematicka knowledge is the use of models to gain an insight to the fundamentals of a mathematical problem and thus seeing how it works. After this one can then break down the mathematical procedure embedded or used it aid the model manually in other to grasp the full concept of the principle.
Answer:

Step-by-step explanation:
Given

Required
Determine the test statistic
Let the dataset of stick be A and Liquid be B.
We start by calculating the mean of each dataset;

n, in both datasets in 6
For A



For B



Next, calculate the sample standard deviation
This is calculated using:

For A




For B




Calculate the pooled variance




Lastly, calculate the test statistic using:

We set

So, we have:


The equation becomes




<em>The test statistic is 31.29</em>
Answer:
the formula to find slope is m=y1-y2/x1-x2
using this formula 8-6/8-(-4)
=2/8+4
=2/12 simplify
=1/6
Answer:
