WebbThe first few steps (Step 1 - Step 3) are exactly the same as the rejection region or p-value approach. The next part will discuss steps 4 - 6 for both approaches. Rejection Region Approach Steps 4-6 Step 4: Find the appropriate critical values for the tests. Write down clearly the rejection region for the problem. Left-Tailed Test WebbIf we had decided at the outset to test at the 10% level of significance, the critical value defining the rejection region would be, reading from Figure 12.4 "Critical Values of Chi-Square Distributions", χ α 2 = χ 0.10 2 = 2.706, so that the rejection region would be the interval [ 2.706, ∞).

WebbH0 : p >= 0.3; Ha : p < 0.3. With the rationale that H0 must include the equality, which in this case is greater or equal to 30%. Her solution then failed to reject the null hypothesis and concluded that the researcher's claim is therefore correct. To me this seems like assuming the claim to be true to begin with and giving it the benefit of ... WebbWhat is the rejection region for a two-tailed test with a 95% level of confidence? If you are using the 95% confidence level, for a 2-tailed test you need a z below -1.96 or above 1.96 before you say the difference is significant. For a 1-tailed test, you need a z greater than 1.65. The critical value of z for this test will therefore be 1.65. southport aba coaching https://gonzalesquire.com
