Assignment Instuctions and data attached.
In the first part of the project you will use the
appropriate technique to use for each of the following questions.
·
Is
there a significant difference in the mean crime rate for Southern states and
the mean crime rate for Northern states? Use the original crime rates.
·
Is
there a significant change in crime rates over the ten years between the first
and second data collections?
·
Was
there a significant correlation between crime rate and police expenditures at
the time of the first collection of data? To determine this, perform a simple
linear regression for these variables including a scatterplot, r, r2,
interpretation of r2 in the context of the problem, determine if
slope is significant, and state what slope indicates in the context of the
problem.
·
Was
there a significant correlation between crime rate and police expenditures ten
years later? This should be answered using the same guidelines as the previous
question.
