My activities in math 1280 course during the Sixth week:
Saturday 3/06/2021: Preparation.
● I had read unit 6 to get a quick review highlighting the valuable
information needed for me.
Sunday 3/07/2021:

Tuesday 3/09/2021: Study.
● I had watched some videos from khan academy website in probability
and distributions topics related to the unit 6 from this course.
Wednesday 3/10/2021: Answering the assignments.
● I had posted in the unit 6 discussion forum and I did reply to 3 of
my peers' answers.
Thursday 3/11/2021: Finalizing.

2. Vocabulary and R functions (be sure to include an APA citation)
a.) The normal distribution: According to Yakir (2011), normal distribution is a very common and
generic distribution that can be used for a lot of values that are continuously distributed over its sample
space. This distribution is usually shaped like a bell and has a consistent and symmetrical wave to it.
b.) pnorm() – a function to calculate probability or cumulate distribution.
3.Task
With qnorm() function returns the quantiles with the mean and standard deviation. It gives the
upper and lower tails.
So, in this case, let us suppose that the lowest 1% will have a mean of 10 while the standard
deviation will be 3.
> qnorm(0.01,mean=10,sd=3)
