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;

\sum \frac{(O_i-E_i)^2}{E_i } \\\\

Where,

\rm O_i is the observed value

\rm E_i is the expected value

The chi-square test statics is;

\rm( \frac{18-18}{18} )^2 +( \frac{14-18}{18} )^2 + (\frac{24-18}{18} )^2+( \frac{16-18}{18} )^2 \\\\ 0+ \frac{16}{18}+ \frac{36}{18} +\frac{4}{18}\\\\ \frac{56}{18} \\\\ 3.11

Hence, the chi-squared test statistic will be 3.11.

The inequality 10.45b + 56.50 &lt; 292.67 is used to find the number of boxes (b) that can be loaded on a truck without exceedin
nordsb [41]

Question :

The inequality 10.45b + 56.50 < 292.67 is used to find the number of boxes (b) that can be loaded on a truck without exceeding the weight limit of the truck. The solution is written as {b | b < 22.6}. Which statement best describes the meaning of the solution?

The truck can hold more than 22 boxes.

The truck can hold more than 23 boxes.

The truck can hold up to 22 boxes.

The truck can hold up to 23 boxes.

Answer:

Option C: The truck can hold up to 22 boxes.

Explanation:

Given that the inequality is 10.45b + 56.50 < 292.67 is used to find the number of boxes can be loaded on a truck without exceeding the weight limit of the truck.

To determine the number of boxes, let us solve the inequality.

Thus, we have,

10.45b + 56.50 < 292.67

Subtracting both sides by 56.50, we get,

10.45b  < 236.17

Dividing both sides by 10.45, we have,

b

This means that the number of boxes that can be loaded on a truck without exceeding the weight limit of the truck should be lesser than 22.6

Therefore, the truck can hold up to 22 boxes.

Hence, Option C is the correct answer.

I NEED HELP AGAIN YALL
ludmilkaskok [199]

Answer:

y = 3x + 2

Step-by-step explanation:

First you want to know what the slope intercept form is. y = mx + b. Now take two points from the table and put them in the equation  and get the slope of 3. Now we have y = 3x + b. To find b we need to plug in any point into the equation. I chose (-1, -1). -1 = 3(-1). Solve and you get 2. Now we are left with y = 3x + 2
