The chi-squared test statistic will be 3.11. The test statistic is contrasted with a predicted value based on the Chi-square distribution.
<h3>What is the chi-squared test statistic?</h3>
Finding the squared difference between the actual and anticipated data values, then dividing that difference by the expected data values, constitutes the test statistic.
The formula for the chi-squared test statistic is;
Where,
is the observed value
is the expected value
The chi-square test statics is;
Hence, the chi-squared test statistic will be 3.11.

The picture is how I solved it and it will be correct
Answer:
B
Step-by-step explanation:
In order for something to have infinite solutions, both sides need to be equal to each other.
Example:
3x + 7y = 7y + 3x
That has infinite solutions
3x + 7y = 7x + 3y
That is not equal to each other because the variables are different.
Hope I helped :)
We have been given two inequalities and . We are asked to find the integers that satisfy both inequalities.
Let us solve for our 1st inequality.
Upon combining our both inequalities, we will get:
This means that solution of our inequalities is x values greater than and less than .
We know that integers between and are: .
Therefore, our solution would be .
