A researcher conducts a Wilcoxon signed-ranks test to investigate the effectiveness of a new mindfulness app on reducing anxiety scores. The analysis of the data yields an observed probability value of p=0.034p = 0.034p=0.034.
Which of the following statements correctly describes the statistical significance of this result?
Significant at the 1%1\%1% level (p<0.01p < 0.01p<0.01) but not at the 5%5\%5% level (p<0.05p < 0.05p<0.05)
Significant at both the 5%5\%5% level (p<0.05p < 0.05p<0.05) and the 1%1\%1% level (p<0.01p < 0.01p<0.01)
Significant at the 5%5\%5% level (p<0.05p < 0.05p<0.05) but not at the 1%1\%1% level (p<0.01p < 0.01p<0.01)
Not significant at either the 5%5\%5% level (p<0.05p < 0.05p<0.05) or the 10%10\%10% level (p<0.10p < 0.10p<0.10)
