We are on week four, time is going by fast. Thursday 28, got home and went strait to my office, I want to get the class started, I want to study as much as I can to see if I can make it up for the previous week, I am not happy about my graded test. I am still frustrated because I think that I understand all the definitions and formulas and how to get them, but it seems like that it’s not always the case, like a student commented grading my assignment may be I am trying to hard on something that is very simple.
Well, we have new material and more material it is definitely getting harder, I am not sure where I am going to get the extra time to study, I do not think this class can be covered in the average 15 or 18 hours a week, I think we need …show more content…
I think I got most of the answers right, but I do not know for sure, that is what I said last week and I was wrong.
Monday, I am finishing my assignment to get it ready for submission, I was going to finish it yesterday but I got stuck on a couple questions, buy the way, I found another typo under the solve exercises section under chapter 4, question 4.1 calls for a table 4.6, well you actually need table 4.4 for that there are not 4.6 table.
It is Tuesday night and I am just providing feedback in the discussion forum, the Professor was not kidding when she said that we need extra hours this week. I am also starting my learning journal, man it’s going to be a long night, hopefully I can also do the self –quiz tonight, will see.
Wednesday, final weekday, it is going to be another long night, I got home late but I have to finish the supplementary exercise for the unit, not a good week, let’s hope hat next week we can breathe a little …show more content…
Vocabulary and R functions
a) What does the symbol x-bar represent?
Represents the sample mean.
b) What does the Greek letter mu (μ) represent as it was used in this week's lessons?
It was used to represent the entire population.
c) What is the difference between x-bar and mu?
Well, the x-bar is the sample mean used to estimate a sample of a population while mu is the true mean, used to estimate the whole population.
3. Mean
a) Many people already know how to find the mean (average) of a sample of data by "adding all the numbers and dividing by the number of values in the dataset." Read Chapter 4, and then describe, in your own words, another method of finding the mean by using the sample space (list of possible values) and probabilities (the technique is in the book).
To use the sample space to get the mean, we have to collect all potential values then multiply each of them by its probabilities to then add those values to get the possible outcome
Create a list of seven, 2-digit numbers (with no duplicates) and another set of seven probabilities (with no duplicates). The probabilities must add to 1.
Values: 11, 22, 33, 44, 55, 66,
