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 } \\\\](https://tex.z-dn.net/?f=%5Csum%20%5Cfrac%7B%28O_i-E_i%29%5E2%7D%7BE_i%20%7D%20%5C%5C%5C%5C)
Where,
is the observed value
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](https://tex.z-dn.net/?f=%5Crm%28%20%5Cfrac%7B18-18%7D%7B18%7D%20%29%5E2%20%2B%28%20%5Cfrac%7B14-18%7D%7B18%7D%20%29%5E2%20%2B%20%28%5Cfrac%7B24-18%7D%7B18%7D%20%29%5E2%2B%28%20%5Cfrac%7B16-18%7D%7B18%7D%20%29%5E2%20%5C%5C%5C%5C%200%2B%20%5Cfrac%7B16%7D%7B18%7D%2B%20%5Cfrac%7B36%7D%7B18%7D%20%2B%5Cfrac%7B4%7D%7B18%7D%5C%5C%5C%5C%20%5Cfrac%7B56%7D%7B18%7D%20%5C%5C%5C%5C%203.11)
Hence, the chi-squared test statistic will be 3.11.

Answer:
0.24
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an even will happen or not happen is 1.
Given that the spun has 10 sections 3 red, 3 blue and 4 green, the probability of not getting green
= (3 + 3)/(3 + 3 + 4)
= 6/10
The probability of getting green
= 4/10
Hence the probability of getting not green then green
= 6/10 * 4/10
= 24/100
= 0.24
