I'm lost no how to find the cutoff rejection region and which table to use?
This is an example,
Data
n 34
X-bar 10.3
s 3.1
98% Confidence Interval for µ is
10.3 ± 2.33 x 0.5316
= (9.0632 , 11.5368)
Hypothesis
H0: µ ≤ 9
H1: µ > 9
Tests Z-stat = 1.3 = 2.4452
Statistic 0.5316
Significance Level = 0.01
Rejection Region =
Tail = RIGHT
Cutt -Off = Z-alpha = 2.326
Decision = Reject H0
p-value = 0.0072
I understand how they reject H0, but I am lost how they got 2.326. I think it's in the Z-table but I'm not sure, can someone explain to me clearly. It would also help if you can tell me how to find 0.0072 for the p-value.
