I need help with CRJ 511 assignment.
(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, assume 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.
2.(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, assume that the variances of the two groups are unequal. 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.
3.(1)Use the Recidivism.xls data, conduct an ANOVA (alpha= .05) in Excel to determine whether there is a significant difference in AGE across different CRIME (1=violent, 2=property, and 3=drug). 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.
