Can equal variances be assumed if Levene's test statistic is 0.68? (significance level of P< 0.5)
Can equal variances be assumed if Levene's test statistic is 0.68? (significance level of P< 0.5)
Homework Answers
Since p value is less than the level of significance(P<0.5), we reject the null hypothesis. In Levene's test, we assume that the variances are equal in the null hypothesis. Since we reject the null hypothesis in this case, we cannot assume equal variances.

Identify the null and alternative hypothesis, significance level, test that will be used, test statistic, P-value, conclusion about the null hypothesis, and state the final conclusion that addresses the original claim in nontechnical terms. In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.10 significance level, test the claim that more than half of all those using the drug experience relief.

2. Look at the Independent samples t-test table to get your t
calculated, df, and significance. Read the line that says “equal
variances assumed”. Remember that significance level will appear in
the Sig (2-tailed) column. Any value that is smaller than .05 will
be significant at the .05 level or higher. In a sentence describe
the results and report them in APA style, including r2
and evaluation (you will need to calculate r2 by
hand).
