If the first set of data is the offender age and the second set is categorical (0 and 1) for recidivism, how do you compare the two in a t-test? I thought you couldn't calculate a mean from categorical data.


(1) Use the Recidivism.xls data, conduct an independent sample t-test (alpha= .05) in Excel to
determine whether there is a significant difference in AGE between those who recidivated
(RECIDIVISM=1) and those who did not recidivate (RECIDIVISM=0). For this t-test, as-
sume that the variances of the two groups are equal. Copy and paste the Excel output here.
In your summary, please discuss the null hypothesis, alternative hypothesis, the result of this
hypothesis test, and interpret the result.
