Review the SPSS output file which reports the results of the independent t-test to compare the mean price per 6-pack for regular vs. reduced calorie brands of wheat beer. Answer the following questions based on your observations of the SPSS output file:
- Is the F-value for Levene's Test for Equality of Variances significant (that is, is the p < .05)? What is the exact significance level? Note: if the Levene's Test for Equality of Variances is significant, then equal variances cannot be assumed.
- Which t-value should you use now that you know whether or not equal variances can be assumed? What is that t-value?
- What is the two-tailed significance level for that t-value? State the exact significance value. Report the results of the t-test as follows: t(df value) = ___, and p-value.
- Is there a statistically significant difference between the price per 6-pack of regular beers versus reduced calorie beers?
