Step 3: After aggregating the data, a one sided t-test was applied to compare the crime rates between NYC and the rest of the state
H0: There is no difference in the index crime rate per 1000 people between NYC and rest of the state. Significance 0.05
Ha: The index crime rate per 1000 people for NYC is greater than rest of the state. Significance 0.05
P-value was less than 0.05 so we rejected the Null hypothesis. The crime rate per 1000 people in NYC is greater than the rest of the state. This is along expected lines.
