R Assignment #4
 

General Purpose

General Purpose of these Assignments: The purpose of these R Assignments is to give you some pointed, direct practice in using R. As such, these are designed to be quick and to the point (less than 10 minutes each). They are also designed to give you a place to return if you forget how to perform some analysis in the future.

Please supply your results in the form below. Clicking on “Click to Check Your Answers” will allow you to see which as correct and which are not. When all are correct (and you can try as many time as you wish), you will be allowed to send your answers to me for credit by clicking on “Click to Email Your Results.” You only receive credit when this is submitted (with all answers correct).

This assignment is due at the start of the class period on

Monday, January 8, 2024.

With that being said, if this R Assignment is available, which is could be until approximately 11:59 pm (CST), then you are able to work on it.

As expected, these are graded according to the syllabus (all or nothing). Please review the appropriate section in the syllabus for more information. Also, if this is not submitted before it is due, then it counts as a zero.

Specific Purpose

Specific Purpose: Specifically, for this particular assignment, you are proving to me that you followed along with SCA 0.

The Problems

For this particular assignment, you will base all answers on the statistical computing activity we did in class (SCA 0). So, in effect, you are merely reporting your results (which will match everyone else’s results if you did it correctly). [As usual, round to at least four decimal places.]

  1. What is the mean of the variable x?
  2. What is the median of the variable y?
  3. What is the standard deviation of the variable z?
