For a two-tailed hypothesis test with α = .05 and a sample of n = 16, the boundaries for the critical region are t = ±2.120.
When is a researcher at risk of making a Type II error? Group of answer choices: whenever H0 is rejected whenever H1 is rejected whenever H0 fails to be rejected The risk of a Type II error is independent of the decision from a hypothesis test.
A researcher is using a two-tailed hypothesis test with α = 0.01 to evaluate the effect of a treatment. If theboundaries for the critical region are t = ± 2.845, then how many individuals are in the sample?A. n = 23B. n = 22C. n = 21D. n = 20E. cannot be determined from the information given
Find the quantity (deviance) for testing the hypothesis H0 and the pvalue used
Determine which of the following statements are true about the critical region. The critical region is a term used when the null hypothesis is rejected. The critical region is comprised of extreme sample values that are very unlikely to be obtained if the alternative hypothesis is true. The critical regions is determined by the alpha level. The critical region is comprised of extreme samples values that are very unlikely to be obtained if the null hypothesis is true
For each of the following statements, formulate the null and alternative hypothesis. Indicate whether the appropriate test will be one tail or two tail. Finally, sketch a diagram that shows the appropriate location of the “rejection” region(s) for the test. “The average GMAT score for MBA students is at least 750.” “The average worker misses an average of three days of work every month.” “The average cost of the course books is no more than $120.”
