Question:

For each of the following situations, find the critical value for z or t.
a) Ho: ( = 105 vs. HA: ( ≠ 105 at ( = 0.05; n = 61.
b) Ho: p = 0.05 vs. HA: p > 0.05 at ( = 0.05.
c) Ho: p = 0.6 vs. HA: p ≠ 0.6 at ( = 0.01
d) Ho: p = 0.5 vs. HA: p < 0.5 at ( = 0.01; n = 500.
e) Ho: p = 0.2 vs. HA: p < at ( = 0.01
