What is the critical value for 0.04, left tailed test? I don't know what to put as the %?! I also don't understand what to look up in the E table for the value of Z?!
What value is 0.04? What is table E? We do not have your text available.
If E gives areas under the normal distribution, the Z score is typically on the left side. If you are looking for P = .04 for a one-tailed test, use the column labeled something like "proportion in smaller area." If it is .04 or less, the result is significant.
