Question 6A one-way within-groups ANOVA on 2 and 15 degrees of freedom results in an Fstatistic of 3.12. What decision should be made about the hypothesis based on thisstatistic?Reject the null hypothesis and conclude the independent variable has no effect.Fail to reject the null hypothesis because the Fstatistic does not exceed thecritical cutoff.Fail to reject the null hypothesis and conclude there is no effect of theindependent variable.Reject the null hypothesis and conclude there are differences among the levelsof the independent variable.

The one-way ANOVA test is used to compare the means of more than 2 groups. This test also used to…

For an ANOVA comparing three treatment conditions, what is stated by the null hypothesis (HO)? Question 14 options: There are no differences between any of the population means. At least one of the three population means is different from another mean. All three of the population means are different from each other. None of the other choices is correct.
When investigating a question involving a scale dependent variable (IV) with three or more variables in which different participants receive each level of the IV, a one-way between-groups ANOVA is the appropriate test to employ. False True
test statistic 0.572 and p-value of 0.2837 are INCORRECT
Suppose a hypothesis test was performed with a level of significance of 0.05. Then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up rejecting the null hypothesis in error. True False
We use the results of our first step to calculate a test-statistic. Why is this important and how does it relate to the concept of z-score, What is a p-value? What role does it play in the rejection of the null hypothesis? What does it mean to reject the null hypothesis? Does that guarantee that the null hypothesis is false?
You wish to test the following claim (Ha) at a significance level of a = 0.002. = Ho: P₁ Ha: P1 P2 P2 You obtain a sample from the first population with 594 successes and 78 failures. You obtain a sample from the second population with 558 successes and 44 failures. The test statistic is...

O There is sufficient evidence to support that the first population proportion is less than the second population proportion. There is not sufficient evidence to support that the first population proportion is less than the second population proportion.
If a hypothesis is rejected at significance level α = 0.01, is it possible that the hypothesis is not rejected if the same test was done at significance level α = 0.05 (with everything else staying the same)?
For an ANOVA comparing three treatment conditions, what is stated by the null hypothesis (HO)? Question 1 options: There are no differences between any of the population means. At least one of the three population means is different from another mean. All three of the population means are different from each other. None of the other choices is correct.
n engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 160 engines and the mean pressure was 7.7 pounds/square inch (psi). Assume the population variance is 0.36. If the valve was designed to produce a mean pressure of 7.8 psi, is there sufficient evidence at the 0.01 level that the valve performs below the specifications? Step 2 of 3: Find the P-value for the hypothesis test. Round your answer to four decimal places.
You are conducting a study to see if the accuracy rate for fingerprint identification is significantly different from 0.23. You use a significance level of α=0.01 H0:p=0.23 H1:p≠0.23You obtain a sample of size n=228n=228 in which there are 70 successes.What is the test statistic for this sample?

The sample data support the claim that the accuracy rate for fingerprint identification is different from 0.23. There is not sufficient sample evidence to support the claim that the accuracy rate for fingerprint identification is different from 0.23.
