If the level of significance (alpha) is 0.05, it means that the probability of rejecting the null hypothesis, when it is false, is 5%. the probability of rejecting the alternate hypothesis, when it is true, is 5%. the probability of rejecting the alternate hypothesis, when it is false, is 5%. the probability of rejecting the null hypothesis, when it is true, is 5%.

The probability of rejecting the null hypothesis, when it is true, is 5%.

Step-by-step explanation:

We know that the level of significance ( denoted as ) is generally the probability of rejecting the null hypothesis when it is true.

Therefore , If the level of significance (\alpha[/tex] ) 0.05, then it means that it is the probability of rejecting the null hypothesis when it is true.

i.e. The probability of rejecting the null hypothesis when it is true= 0.05

In percent :

Hence, the correct option is : The probability of rejecting the null hypothesis when it is true is 5%.
