For a one-sided hypothesis test with a p-value of 0.041, the smallest level of significance at which the null hypothesis can be rejected in a corresponding two-sided test is 10%. This is because the p-value for the two-sided test would be double that of the one-sided test, making it approximately 0.082, which is less than 10% but more than 5%.
