- Use the calculator displays to the right to make a decision to reject or fail to reject the null hypothesis at a significance level of α=0.01. (View the image for the displays) The correct answer is.. A. Since the P-value is greater than α, fail to reject the null hypothesis. B. Since the P-value is greater than α, reject the null hypothesis. C. Since the P-value is less than α, fail to reject the null hypothesis. D. Since the P-value is less than α, reject the null hypothesis.Find the value of the standard score, z, and determine whether to reject the null hypothesis at a 0.01 significance level. Is the alternative hypothesis supported? Ho p= 18.5 meters, H p18.5 meters, n= 144, x = 19.1 meters, o = 1.3 meters %3D The value of the standard score is (Round to two decimal places as needed.)Calculate the r2. Interpret r2 in the context of this study. Report your obtained t score for the test of differences in means, and the obtained p value. Make a statistical decision about the null. Will you reject or fail to reject the null based on these SPSS results? Why?
