Question

For a hypothesis test with the following conditions, find the critical value(s) for z or t:

H₀: p = 0.2 vs. Hₐ: p ≠ 0.2 at α = 0.05
a. -1.96 and 1.96
b. -2.58 and 2.58
c. -1.645 and 1.645
d. -2.33 and 2.33

Answer 1

The critical value(s) for a hypothesis test with the conditions H₀: p = 0.2 vs. Hₐ: p ≠ 0.2 at α = 0.05 can be found using the z-table or t-table, and in this case, the critical values are -1.645 and 1.645.

Step-by-step explanation:

The critical value(s) for a hypothesis test with the conditions H₀: p = 0.2 vs. Hₐ: p ≠ 0.2 at α = 0.05 can be found using the z-table or t-table, depending on the given information. In this case, the alternatives c. -1.645 and 1.645 correspond to the critical values for a two-tailed z-test at α = 0.05.
