WebFind the critical value ze necessary to form a confidence interval at the level of confidence shown below. c=0.82 The level of confidence c is the area under the standard normal curve between the critical values - Zc and Zc. The area outside the critical values is 1 –c, so the area in each tail is (1-c).

WebQ: Find the critical value zc necessary to form a confidence interval at the level of confidence shown… A: The confidence level is 0.92. Computation of critical value: c=0.921-c=0.081-c2=0.04c2=0.96 The… WebA correlation coefficient, usually denoted by rXY r X Y, measures how close a set of data points is to being linear. In other words, it measures the degree of dependence or linear correlation (statistical relationship) between two random samples or two sets of population data. The correlation coefficient uses values between −1 − 1 and 1 1. WebThe critical value is 0.666. 0.708 > 0.666 so r is significant. r = 0.134 and the sample size, n, is 14. The df = 14 – 2 = 12. The critical value is 0.532. 0.134 is between –0.532 and 0.532 so r is not significant. r = 0 and the sample size, n, is five. No matter what the dfs are, r = 0 is between the two critical values so r is not ... fmea process characterization
