What would a two-tailed hypothesis test (with alpha – .05) using this data show about the relationship between the two variables? Justify your conclusions.
Q4. Kyung-Shick Choi, Mitch Librett, and Taylor Collins (2014) found that a gunshot detection system, Shotspotter, significantly reduced the time it took police to respond to a gun-related crime. You are interested in determining whether this faster police response time (x) will lower the crime rate (y) in a given community and, conversely, whether a longer response time is associated with a higher crime rate. You have a small SPSS dataset with the average time it takes the police to respond to a call by a citizen for help in a community as well as that community’s rate of crime. With these data, do or answer the following:
A few things: Where it says “calculate” you will run the appropriate analysis in SPSS using the dataset posted below. You should also draw the scatterplot in SPSS. Instructions for this are provided in SPSS Exercise Q1.
Post your scatter plot and analysis output (specifically, the Model Summary, ANOVA, and Coefficients tables) in the canvas window. Finally, interpret your results consistent with a two-tailed significance test.
Response posts should evaluate and comment on your classmates’ posts.
