At the α = 0.05 level of significance, which one of the following is correct?

A) p-value = α
B) p-value > α
C) p-value < α
D) Not enough information for comparing the values of p and α.

Answer :

Final answer:

Without sufficient information or statistical computations for the provided data set, we can't determine or compare the p-value with the α level of 0.05. Thus, the answer is D) Not enough information for comparing the values of p and α.

Explanation:

The question is essentially asking us to compare a computed p-value with a specified level of significance (α). However, there's insufficient data or statistical computation method provided to determine the p-value for the given data set. Thus, we are unable to compare the p-value with the α level of 0.05. Therefore, the correct answer is D) Not enough information for comparing the values of p and α.
