Find the P-value for the hypothesis test with the standardized test statistic z. Decide whether to reject H0 for the level of significance α. Left-tailed test z = – 0.85, α = 0.05

The P-value for a hypothesis test is P = 0.007. Do you reject or fail to reject H0 when the level of significance is α = 0.01?

What is the z value of question 3?
