What This Document Is
This is a lab assignment – Lab Assignment One – for Introduction to Statistical Methods (STA 205) at Northern Kentucky University, from Fall 2018. It’s designed to give students practice working with normal distributions, a core concept in statistics. Students are expected to complete the questions on a separate sheet of paper and submit it to their lab instructor.
Why This Document Matters
This assignment is for students enrolled in STA 205. It’s a graded exercise intended to reinforce understanding of normal distributions through practical application. Completion of this lab is likely a required component of the course grade. It builds foundational skills needed for more advanced statistical analysis.
Common Limitations or Challenges
This document *is* the assignment itself. It does not provide completed solutions, explanations of statistical concepts, or detailed instructions on *how* to solve the problems. Students will need their course materials (textbook, lecture notes) and a working knowledge of normal distributions to complete it.
What This Document Provides
The assignment includes five problems. These problems cover:
* Identifying curves with the same mean and standard deviation.
* Calculating probabilities related to iPad battery life, modeled as a normal distribution.
* Analyzing a scenario involving Kentucky unemployment rates, identifying observational units, parameters, and sampling methods.
* Applying the Empirical Rule to attendance at NKU basketball games.
* Working with the normal distribution of Best Picture Oscar winner lengths.
