Statistic Final Project

INTRODUCTION: Studying statistical data on determining whether black murder rates are higher in the US than whites by total number of murders.

DATA: I will be comparing the FBI's 2019 Expandable Homicide Data Table 6. Inside it includes single victim/single offender details for murders in 2019. I will be correlating it with the Census.gov data under Quick facts (US).

INSTRUCTIONS

Please find the Correlation, Confidence Interval, and Hypothesis Testing

HINT:

Ho: p=0 (there is an association between race and murder rates in the US)

H1: p<>0 (There is an association between race and murder)

Please use 80% confidence level.

And compare significance of a Correlation with a=0.80 or 80 % Confidence Interval. In 0.000<0.80 = Reject Null Hypothesis

In addition to the correlation coefficient, for one of your variables you should construct a 80% confidence interval, and conduct a hypothesis test where you test that variable against the hypothesis that is 0.
