A researcher plans to conduct a test of hypotheses at the α = 0.10 significance level. She designs her study to have a power of 0.7 at a particular alternative value of the parameter of interest. The probability that the researcher will commit a Type I error is: 0.7. 0.9. 0.1. equal to the PP‑value and cannot be determined until the data have been collected.
i need 9 though 15 please and thank you STAT 2480 Chapter 9: Significance Tests About Hypotheses Across 1. In a significance test, the null hypothesis is presumed to unless the data give strong evidence against it. Down 2. The hypothesis is usually a statement of no treatment effect the null hypothesis 3. A Type 1 Error is when we when it is true. 4. When the null hypothesis is rejected because the P- value is less than or equal...
You conduct a hypothesis test about a population proportion p at a significance level of a = .01 using a random sample of size n = 38. Your test statistic follows a standard normal distribution when the null hypothesis is true as an equality, and its value obtained from the sample is z = -2.75. Use the Distributions tool to help you answer the questions that follow. Select a Distribution Distributions 0 1 2 3 If you perform a lower...
What can be said about the relationship between the significance and the effect size of a hypothesis test? Group of answer choices The significance of a test is not determined by the effect size alone. A significant test result leads to a large effect size while a non-significant test result leads to a small effect size. The effect size is determined by the alpha level while the significance of a test is not. The effect size is always the same...
. We would like to conduct a hypothesis test at the 10% level of significance to determine whether the true mean score of all players in a bowling league differs from 150. The mean and standard deviation of the scores of 12 randomly selected players are calculated to be 170 and 16, respectively. Scores of all players in the league are known to follow a normal distribution. The P-value of the appropriate test of significance is

You are asked to conduct a simulation and run a hypothesis test at a significance level of 0.10. Based on your simulation, you find that the p-value is 0.051. What does this mean for your hypothesis test? 1. Since the p-value is greater than the significance level, you must fail to reject the null hypothesis. 2. Since the p-value is less than the significance level, you must fail to reject the null hypothesis. 3. Since the p-value is less than...
The p-value is NOT equal to α, the level of significance of the hypothesis test. True or false?
An interval of numbers within which the parameter value is believed to fall. A number such that we reject Ho if the p-value is less than or equal to that number. The numerical value obtained from a statistical test. A statistical statement that says a difference between the parameter and a specific value exists or states that there is a difference between two parameters. The error that occurs if you reject the null hypothesis when it is true. 10. The...
