To solve for z, we need to use the standard normal distribution and find the z-score corresponding to a probability of 0.01. For a lower level test, we use a one-tailed test and look for the z-score corresponding to the 1% level of significance. This z-score is -2.33 (which is the 1% critical value for a one-tailed test) and is the answer.
