Question at position 35 In the context of inferential statistics, a confidence level of .05 means thatthe researchers are confident about the methodology of their research to an extent of 5 percent.if the odds are .05 or less that the differences are due to chance, the results are considered statistically significant.if the study is conducted five times using the same variables and conditions, the result would be the same.the confidence level of participants in a research study is calculated to be .05.

Topic clarity: this question centers on the meaning of a confidence level (0.05) in inferential statistics and its relation to statistical significance.
Option 1: 'the researchers are confident about the methodology of their research to an extent of 5 percent.' This wording misinterprets the concept. A 0.05 confidence level does not express confidence in the methodology itself; it expresses a threshold for rejecting a null hypothesis, not a judgment about methodological quality. 
Option 2: 'if the odds are .05 or less that the differences are due to chance, the results are considered statistically significant.' This aligns with the standard interpretation: a p-value at or below 0.05 indicates that observed differences are unlikely under the null hypothesis, i.e., statistically significant. The phrasing uses 'odds' where the conventional term is 'probability' or 'p-value,' but the essential idea is correct. 
Option 3: 'if the study is conducted five times using the same variables and conditions, the result would be the same.' This is not implied by a 0.05 confidence level. Repetition across independent samples might yield varying results due to sampling variability; a fixed 0.05 level does not guarantee identical results across replications. 
Option 4: 'the confidence level of participants in a research study is calculated to be .05.' This describes participant confidence or subjective belief, which is irrelevant here. Confidence level in statistics refers to a property of the interval estimator, not a measure of participants' beliefs. 
In summary, the second option conveys the correct statistical interpretation that a p-value at or below 0.05 indicates statistical significance, while the other choices misstate what a 0.05 confidence level represents or mix up related concepts with incorrect implications.
