Extracted text: (b) The following data in Table Q4(b) were collected to determine the performance of energy coverage probability for wireless powered hybrids networks from three different predefined threshold. Table Q4(b) Average coverage probability value for various predefined threshold Yı = -60 16.2 17.1 16.6 16.3 Y2 = -70 15.1 15.2 15 13.2 14.7 Yз—80 16.4 17.3 16.8 17.2 15.3 18.2 The populations are not normally distributed with unequal population variances. Using a suitable non-parametric statistical test, is there enough evidence to reject the hypothesis that all thresholds have the same average coverage probability value? How would you write the hypotheses statement for this problem? What is the suitable statistical distribution to find the critical value at a=0.05?
