if a hypthosis test produces a z-score in the critical region which decision should be made?
Step by step
Solved in 2 steps
- If the alpha level is changed from a = .OS to a = .01 What happens to the boundaries for the critical region? What happens to the probability of a Type I error?Define the alpha level ad the critical region for a hypothsis test.1. calculate the test statistic 2. Identify the form of the critical region for the current test
- Determine the critical z-score corresponding to αα = 0.15 in a left-tail test. crititical z-score = [three decimal accuracy]With α = .05, (two-tailed test) how are the boundaries for the critical region determined?A researcher decides to lower the alpha level that determines the critical region(s) prior to conducting a hypothesis test. This will increase the power of the hypothesis test. True or False?
- Find the t values that form the boundaries of the critical region for a two-tailed test with α = 0.10 for a sample size ofWhat is the critical region to reject the null hypothesis in this image and where is the accepted region to accept the null hypothesis in this image? List this in relationship to the lower and higher accepted values. Critical region: Accepted region:Define the critical region for a hypothesis test, and explain how the critical region is related to the alpha level.
- An excess of high values for the cases distributed on a graph results in a positive skew in the data?Do you know Cohens D, Critical region boundary/boundaries, and the Estimated Standard Error?Find the t-value that form the boundaries of the critical region for a two-tailed test with a= 0.01 and a sample size of 25.
