Question 9 If the nominal alpha is set to .05, what p value would be considered...
1) The p value we’ve used in PSYC 510 and 515 was set at .05, but others in our field at times use .01. If researchers used the same assessments and sample sizes, lowering the alpha would affect what?
9. A hypothesis test is performed with a significant level of á05 a) If the P-value is.08, is Ho rejected?7 b) If the P-value is .08, are the results statistically significant at 05 level? c) If the P-value is.03, is Ho rejected? d) If the P-value is .03, are the results statistically significant at 05 level?
Question 9 2.5 pts In which of the following situations would you retain the null hypothesis? When your alpha is larger than your p-value. When your positive test statistic is greater than your positive critical value. When your alpha is smaller than your p-value. When you determine your results to be statistically significant.
If your p-value is 0.33 and your alpha level is 0.1 then you would: reject the Ho fail to reject the Ho unable to determine from this information accept the Ho If your p-value is 0.33 and your alpha level is 0.05 then you would: reject the Ho fail to reject the Ho unable to determine from this information accept the Ho If your p-value is 0.33 and your alpha level is 0.01 then you would: reject the Ho fail...
1. If your p-value is p=.0768, what will your decision be at an alpha level of .10? A. Reject Ho B.Do not reject Ho 2. If your p-value is p=.0768, what will your decision be at an alpha level of .05? A. Reject Ho B. Do not reject Ho 3.If your p-value is p=.0768, what will your decision be at an alpha level of .01? A. Reject Ho B. Do not reject Ho
For each of the following possible conclusions, state whether the p-value would have to be less than or greater than 0.05 for you to reach that conclusion. For example, on part a. if you decide to reject the null hypothesis, does that mean your p-value is less than .05 or greater than .05? a. You decide to reject the null hypothesis b. You decide to reject the alternative hypothesis c. You accept the null hypothesis d. You accept the alternative...
Question 3 1 pts The following APA summary was reported for a one-sample t-test (two-tailed, alpha =.05). t(20) = 1.5, p > .05 Which of the following is an appropriate conclusion? The difference is statistically significant. The critical t is 1.5. 20 individuals participated in the study. The difference is not statistically significant.
If alpha is set to .05, what will the level of Type II error be? 0.05 0.95 0 Cannot say Heteroscedasticity occurs when: there are larger values on X than Y. there is a linear relationship between X and Y. more error is accounted for than remains. variability in Y depends on the exact value of X. The variables that are measured throughout the experiment are called: Control Dependent variable Independent variable Responding variable
The results of a single-sample t test are reported as t(44) = −3.35, p < .001, d = −0.50. If alpha is set at .05 in the left tail, what is the correct decision to make regarding the null hypothesis?

need help with this question, please show work by hand no excel,
spss thank you !
Assume you're using an alpha of 05, and a two-tailed test, to make your decision about whether to reject the null hypothesis. Assume that 18 subjects received one of three treatments and produced the data reported in Data Set B. Conduct a one-way ANOVA to see if the means of the three treatments are different on a statistically significant level. Complete an ANOVA...
