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.

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
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
