Milestone 3: Inference
Overview and Objectives
The primary objective of this project will be to perform a few hypothesis tests, make inferences on the test statistics, and state null/alter
native hypotheses. The techniques used in modern inferential research require software beyond our current means (SPSS, R, SAS); however, we are nonetheless able to observe a few examples that are illustrative of the research process.
You will work with populations, samples, and proportions in these exercises. You’ll then determine whether to use a Z-statistic or T-statistic to determine whether to reject the null hypothesis and you’ll also make connections between hypothesis testing and confidence intervals. You’ll have the opportunity to explore real-world datasets in the fields of criminal justice, equity, and surveying.
With a firm knowledge of this statistical concept, you’ll possess the conceptual knowledge necessary to further pursue these techniques if they are of interest to you.
Part One: Crime Analysis from 2016-2017
National law enforcement noticed an overall decline in crimes among US Citizens. This data set records the number of crimes in each state and the percent change from 2016 to 2017. Let’s suppose that leadership would like to conduct a hypothesis test at the 99% significance level that crime has decreased over time (by using percent change). For this part, you should look at the total percent change column to run your test.
Performing the Test
Step 1:Write the null hypothesis/alternative hypotheses below. Determine the tail type.
:     left tail test
Step 2:Perform the Hypothesis Test in Excel. Fill out the cells indicated on the spreadsheet and determine whether to accept/reject the null hypothesis.
Ans : Filled in sheet
Step 3:Find a 99% confidence interval for the percent change from 2016 to 2017 by filling out the cells in the Excel sheet.
Ans:...
