Question 721077: Use the given information to find the P-value. Also, use 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis).
Ho: p = 2/5
H1: p < 2/5; the test statistic is z = -1.68

Use the given information to find the P-value. Also, use 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis).
Ho: p = 2/5
H1: p < 2/5; the test statistic is z = -1.68
----
p-value = P(z < -1.68) = 0.0465
------
Since the p-value is less than 5%, reject Ho.
