Explanation:
Detailed explanation-1: -Answer and Explanation: When a result is said to be statistically significant at 5% level of significance, it means that we don’t have sufficient evidence in favour of the null hypothesis. So we have to reject it when it is statistically significant. So the correct answer is (a).
Detailed explanation-2: -The 5 percent level of significance, that is, = 0.05, has become the most common in practice. Since the significance level is set to equal some small value, there is only a small chance of rejecting H0 when it is true.
