If the level of significance is 005 and the Pvalue is 0043 t

If the level of significance is 0.05, and the P-value is 0.043, the decision would be to

fail to reject the null hypothesis

reject the null hypothesis

make no decision becausethe difference between the level of significance and the p-value is not statistically significant.

use a nonparametric test because normality of the data cannot be established when the results are close.

Solution

Since p-value is less than the level of significance 0.05 so we rejec the null hypothesis. Hence, option (b) is correct.
