Inferential Statistics Analysis and Writeup Purpose: The purpose of this assignment is to develop and carry out an inferential statistics analysis plan and write up the findings.

There are two main parts to this assignment:

● Part A: Inferential Statistics Data Plan and Analysis

● Part B: Write up of Results Part A: Prepare Data Plan, Analyze Data, and Complete Part A of the

The work needs to be on the template below:
