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 Levenes Test for Equality of Variances significant (that is, is the p < .05)? What is the exact significance level? Note: if the Levenes 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?T-TEST GROUPS=Reducedcals(0 1)/MISSING=ANALYSIS/VARIABLES=price/CRITERIA=CI(.95).T-TestNotesOutput Created07-JUN-2013 11:20:55CommentsInputDataC:UsersdonnDocumentsGCU Lead facProject with Judy for modifying PSY845 to introduce SPSSdrinks database -revised for course applications DH.savActive DatasetDataSet1File LabelSPSS/PC+FilterWeightSplit FileN of Rows in Working Data File35Missing Value HandlingDefinition of MissingUser defined missing values are treated as missing.Cases UsedStatistics for each analysis are based on the cases with no missing or out-of-range data for any variable in the analysis.SyntaxT-TEST GROUPS=Reducedcals(0 1)/MISSING=ANALYSIS/VARIABLES=price/CRITERIA=CI(.95).ResourcesProcessor Time00:00:00.02Elapsed Time00:00:00.01[DataSet1] C:UsersdonnDocumentsGCU Lead facProject with Judy for modifying PSY845 to introduce SPSSdrinks database -revised for course applications DH.savGroup StatisticsRegular or reduced calorie for brandNMeanStd.
