For each level of confidence c below, determine the corresponding normal confidence interval. Assume each confidence interval is constructed for the same sample statistics. 17. c=0.85 18. c=0.88 19. c= 0.95 20. c= 0.98 . . . 56.8 62.4 57.7 61.5 57.9 x =59.6 x =59.6 x=59.6 55 56 57 58 59 60 61 62 63 64 55 56 57 58 59 60 61 62 63 64 55 56 57 58 59 60 61 572 x = 59.6 62 55 56 57 58 59 60 61 62 63 64 Drag each normal confidence interval given above to the level of confidence c. 17. 18. 19. 20
