Can equal variances be assumed if Levene's test statistic is 0.68? (significance level of P< 0.5)
You wish to test the following claim (Ha) at a significance level of α=0.001. d denotes the mean of the difference between pre-test and post-test scores. Ho:μd=0 Ha:μd<0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n=127 subjects. The average difference (post - pre) is ¯d=−6.8 with a standard deviation of the differences of sd=24.7 The test statistic's value is (-6.8-0)/(24.7/sqrt(127)) =...
You wish to test the following claim a significance level of α = 0.05 . H o : p = 0.5 H a : p > 0.5 You obtain a sample of size n = 461 in which there are 257 successful observations. What is the test statistic for this sample? test statistic = Round to 3 decimal places. What is the p-value for this sample? P-value = Use Technology Round to 4 decimal places. The p-value is... less than...
The P-Value is the smallest level of significance that would lead to the rejection of the null hypothesis. True False

Determine the test criteria: Specify the level of significance (Type I error associated with the null hypothesis), Determine the test statistic (the appropriate statistical test as mentioned under point 5 above), Determine the critical values (and region(s) if applicable), Calculate the value of the test statistic (obtained value). Make a decision about the null and research hypothesis by comparing the obtained value to the critical value and interpret the results of the data. You can pay attention also to the...
