Interval for the Mean - Econometrics Report - Statistics Assessment Help

Statistics Assessment Task

Questions 1. Report summary statistics for west, early2000, murder_rate, rape_rate, robbery_rate. Interpret each of the means in plain language, thereby characterising a typical observation in the dataset. Your discussion should be no more than three sentences long.

2. Compute 95% confidence interval for the mean of rape_rate and construct a histogram for rape_rate. Provide a brief discussion of your findings. Your answer should be no more than two sentences long.

 3. Construct the following density plots: - Plot 3a: display 2 separate densities for the murder rate in the late 2000s (early2000=0) and early 2000s (early2000=1) within the same graph.

o In other words, the 2 different density plots for the murder rate for the early and late 2000s should be overlaid with each other such that the densities for the murder rate in these respective periods are easily comparable visually.

- Plot 3b: display 2 separate densities for the rape rate in the late 2000s (early2000=0) and early 2000s (early2000=1) within the same graph.

- Plot 3c: display 2 separate densities for the vehicle theft rate in the late 2000s (early2000=0) and early 2000s (early2000=1) within the same graph.
