    Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test the null hypothesis.
    =0.05 for a left-tailed test.
    -1.645
    1.96
    1.645
    -1.96

    Use the given information to find the P-value.
    The test statistic in a right-tailed test is z = 1.43.
    0.500
    0.0434
    0.4236
    0.0764
