Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null
hypothesis (reject the null hypothesis or fail to reject the null hypothesis).

A) 0.0512; reject the null hypothesis
B) 0.9744; fail to reject the null hypothesis
C) 0.0512; fail to reject the null hypothesis
D) 0.0256; reject the null hypothesis

The P-value for a two-tailed test with a test statistic of z=1.95 is 0.0512. Since the significance level is 0.05, we would fail to reject the null hypothesis. Therefore, the correct answer is C, which states that the P-value is 0.0512 and we fail to reject the null hypothesis.
