Find out which of the transformations in Exercises 1 through 50 are linear. For those that are linear, determine whether they are isomorphisms.T(x -h iy

o -= .2 o o z .10 the RBA up to here is .4000 = 1.28 o confidence interval is -1.29 ≤ z ≤ 1.28 - We want to derive the 1-confidence interval for ��� based on a SRS of n elements with n≥30 o = confidence level = given o by definition z we are 1-confident that 1- z ≤ z ≤ z o thus, we are 1-confident that xx̄ +/- z ���/√n sample error: |xx̄ xx̄ - another description of the CI is this: we areconfident that the sample error |xx̄-does not exceed the margin of error z ���/√n Example: give a 99% confidence interval of th
