Question

For a hypothesis test of H₀: p = 0.65 against the alternative H_a: p < 0.65, the z test statistic is found to be -2.35. What can be said about his finding?

The finding is significant at both α = 0.05 and α = 0.01.

The finding is significant at α = 0.05 but not at α = 0.01.

The finding is significant at α = 0.01 but not at α = 0.05.

The finding is not significant at α = 0.05 and α = 0.01.

The finding is inconclusive because we don't know the value of p̂.
