Textbook Question
Chapter 16, Problem 8E
More critical values For each of the following situations, find the critical value for z or t.
a) H0: μ = 105 vs. HA: μ ≠ 105 at α = 0.05; n = 61.
b) H0: p = 0.05 vs. HA: p > 0.05 at α = 0.05.
c) H0: p = 0.6 vs. HA: p ≠ 0.6 at α = 0.01.
d) H0: p = 0.5 vs. HA: p < 0.5 at α = 0.01; n = 500.
e) H0: p = 0.2 vs. HA: p < 0.2 at α = 0.01.

Students have asked these similar questions
The critical value of t at a given alpha level will be smaller than the comparable critical value of z and is much smaller when n is very small.
using the z table (table e), find the critical value (or values) for each.
a. alpha=0.10, two tailed test
b. alpha=0.01, right tailed test
c. aplha=0.005, left tailed test
When testing:
H0: (alpha)1^2=(alpha)2^2.
HA: (alpha)1^2>(alpha)2^2. At (alpha)=0.01, n1=5, n2=6. s1^2=15750 and s2^2=10920, what critical value do we use?
