[2 points] Compute the Sign test statistic K byhaod. ii. [3 points] Compute the zstatistic corresponding to the value of K that you obtained. iii. [3 points] Find the twosided pyalue using the normal approximation to the null distribution of K b. Use the Wdcoxon SignedRani; test to test that the 'center' {pseudomedian} of this distribution is [1. i. [3 points] Compute the SignedRank test statistic S by hand. ii. [3 points] Compute the zstatish'c corresponding to the value of S that you obtained. iii. [3 points] Find the twosided pyalue using the normal approximation to the null distribution of K c. [3 points] Discuss the differences between these two results. Hos.T would you interpret your analysis in each case
