A) 1
B) 9
C) 1.67
D) 0.229
Level Of Significance
A predetermined criterion for decision making in hypothesis testing, representing the probability of making a Type I error if the null hypothesis is true.
Main Effect
In statistics, it refers to the effect of an independent variable on a dependent variable ignoring the effects of all other independent variables.

Final Answer :
D
Explanation :
The level of significance is the probability (p-value) that the result occurred by chance. In this case, the p-value is 0.229, which means that there is a 22.9% chance that the result occurred by chance. The usual level of significance is 0.05 or 5%, which means that we would consider results with a p-value less than 0.05 to be significant. However, in this case, the p-value is higher than 0.05, so we cannot consider the result to be significant at the usual level of 5%. Therefore, the best choice is D, which gives the p-value of the result.
