Answer:

AAS or ASA

Step-by-step explanation:

To prove this congruent, you need 3 corresponding congruent parts. One of the angles are already marked congruent for you (<S and <K). Then WJ is equal to itself (reflexive property) and m<SWJ=m<WJK by alternate interior angles. You know this because the sides are parallel, and WJ acts as the transversal. So there you have it. Triangle SJW is congruent to Triangle KJW by AAS.

Answer:

The true true level of significance of this test is more than 0.01.

Step-by-step explanation:

No standard deviation and we are told that the investigator still used z rather than the more appropriate t - distribution.

This method of using the z-distribution when standard deviation is unknown will definitely result in a smaller critical value and this in turn simply means that the p-value will be smaller than what it should really be.

Thus, it means the critical value is getting closer to the mean value than the way it should be.

Therefore, means that for a given significance of 0.01 and using the z-distribution under this no standard deviation situation, the true true level of significance of this test is more than 0.01.
