PAGE # ETC NOT IN BoOK BUT SIMILAR TO #7 ON 371 PROBLEM 92% CONFIDENCE A. Za FINDTHE Z (ALPHA DIVIDED BY 2 VALUE FOR EACH OF THESE FROM A THROUGH C: 93% CONFIDENCE Za/2 96% CONFIDENCE 2a/2 ARE THE INTERVALS IN THE 3 QUESTIONS ABOVE ONE Add-on D Problems TAIL RIGHT, ONE TAIL LEFT Not in text OR TWO TAILS? IF YOU ARE WORKING ON 95% CONFIDENCE, How MUCH (%) IS IN EACH TAIL IF YOU ARE WORKING ON 99% CONFIDENCE, HOW MUCH (%) IS IN EACH TAIL ? TRUE-FALSEIF A PROBLEM STATES ALPHA 98%, THEN EACH TAIL HAS 2%INIT

Explanation / Answer

a) given Alfa = 0.02

Z(0.02/2) = Z0.01 = 2.33

b) Alfa = 0.03

Z (0.03/2) = Z0.015 = 2.1701

c) Alfa = 0.04

Z (0.04/2) = Z 0.02 = 2.0537

d) all are two tailed values
