Yes, the formula for the volume of a prism is the area of the base multiplied by the height of the prism. To find the area of the base since it's a triangle is 1/2 base x height. Which would be 1/2(4)(12)=24. Then you would take that number and multiply it by the height of the prism. Which would be (24)(6)=144 cubic units.

If the level of significance (alpha) is 0.05, it means that the probability of rejecting the null hypothesis, when it is false,
Kaylis [27]

Answer: 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 \alpha ) 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 : 0.05=5\%

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