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.

Bowling costs 15 dollars per person and 3 is amount of money per game it cost to play. If you play 5 games then you pay a total of 30 dollars.
Answer:
12
Step-by-step explanation:
Let n = the number.
2n - 7 = n + 5
n = 12
Let’s check if we got the right answer by substituting 12 for n into the original equation.
2*12 - 7 = 12 + 5
24 - 7 = 17
17 = 17

It
is a linear function because the rate of change is constant: for each
increase of 1 unit in x, there is a decrease of 4 units in y: ⇒ slope = - 4
Remember to include the two points
of intersection in your table. Analyze the two functions; they are there (0,36) and (4, 20)
Answer the
following reflection questions in complete sentences. What is the domain
and range of the rainbow?
Explain what the domain and range represent.
Do all of the values make sense in this situation? Why or why not? What
are the x- and y-intercepts of the rainbow? Explain what each intercept
represents.
The domain is all the real values of x between - 6 and 6: - 6 ≤ x ≤ 6
The range is all the values between 0 and 36: 0 ≤ y ≤ 36
The domain represents the horizontal distance between the extremes of the rainbow at the ground.
The range represents: the altitude of the rainbow from the ground (y = 0). The height is at x = 0, y = 36.
The x-intercepts are - 6 and 6, that is the opening of the rainbow at the ground level.
The y-intercept is when x = 0, it is y = 36, and is the height of the rainbow.
Is the linear function you created positive or negative?
Explain. What are the solutions or solution to the system of equations
created? Explain what it or they represent.
The linear function is positive and decreasing. It is positive because it goes above the x-axis, this is y ≥ 0.
The solutions where already signaled: (0,6) and (4, 20). They are the points at which the drone intercepts the rainbow.
