Obtuse I think because 50+40+11=101
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>
We can factorize the equation given:
<span>5 • 20 + 5 • 3
= 5(20 + 3)
= 5(23)
= 115</span>
Answer:
Therefore, x = -2m+4/-n-1
