1.) 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). The test statistic in a two-tailed test is z = 1.95. Group of answer choices 0.0256; reject the null hypothesis 0.9744; fail to reject the null hypothesis 0.0512; reject the null hypothesis 0.0512; fail to reject the null hypothesis 2.)
