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.

Lana's toy boat can sail 7 1/2 yards in 4 1/6 minutes. How far would it sail in 8 3/4 minutes if kept the same pace?
Inessa [10]

Answer:

63/4

Step-by-step explanation:

Let the sails yard in 8 3/4 minutes= X

7 1/2 yards sails= 4 1/6 minutes

X = 8 3/4 minutes

Let us Convert the fraction to improper fraction

4 1/6 minutes= 25/6 minutes

8 3/4 minutes= 35/4 minutes

7 1/2 yards sails= 15/2 sails yard

Then

15/2 yards sails= 25/6 minutes

X = 35/4 minutes

If we cross multiply

25/6 X = 15/2 × 35/4

25/6 X =525/8

6 × 525= (25× 8)X

3150= 200X

X= 3150/200

X=63/4

Tina is saving to buy a notebook computer. She has two options. The first option is to put $200 away initially and save $10 ever
Daniel [21]
It would be 5 months until the price for the notebook computer would be the same. Here are the steps to solving the problem:

1. Step up the equation, 200 + 10x = 100 + 30x
2. Subtract 100 from both sides and Subtract 10 from both sides,
100 - 200 =  10x + 30x, 100 = 20x
3. Solve for x, 100/20 = 20x/20, x= 5
