Asked by Christina

Find the P-value for a left tailed hypothesis test with a test statistic of z= -1.77. Decide wether to reject the null if the level of significance is alpha= 0.05.

Please help I've tried everything and I can't figure out how to get the right answer..

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability of Z = -1.77. Is the probability in the smaller area < .05?
