If we are testing the null hypothesis H₀; p < or = 0.75 versus Hₐ: p > 0.75 and we compute our standard score (z-score) to be z = 6,5, then:
a. we have significant" results with a p-value that is bigger than 0.05
b. we have significant" results, with a p-value that is less than 0.05
c. we fail to have convincing evidence that pls > 0,75
d. we have convincing evidence that p is bigger than 6.5
