, Quizzes and graded assignments in MATH1280 are NOT group projects. Please answer
the questions and do not share the questions or answers with others or accept advance
access to questions or answers from others.
1) The first task is to review some information that might be useful later:
a) Write a brief definition of the word "quartile" as we have used it in previous weeks. Be
sure to provide a citation:
A quartile describes a division of observations into four defined intervals based on the
values of the data and how they compare to the entire set of observations. (Liberto,
2021)
b) Write a brief definition of the word "quantile" as it might be used in statistics. Be sure
to provide a citation (do not cut and paste... use your own words to summarize what
you discovered):
Quantiles show a certain part of the data and they determine a certain limit whether
above or below the certain limit of distribution. The examples of quantiles are
percentiles and quintiles. (Yakir, 2011)
c) From within interactive R, enter the command shown below (the command shows a
help page for the pbinom command). Provide a very brief description of the arguments
that are passed to the pbinom() command ("arguments" in computer programming are
the options that you give to a function so that the function can calculate what you want
it to). Note that one of the arguments is lower.tail = TRUE, and because there is a value
assigned to it with the equals sign, it means that if you do not enter a new value for
lower.tail, it will be set to TRUE by default. Do not type the ">" into R, it is the command
prompt:
> ?pbinom
The usage
pbinom(q, size, prob, lower.tail = TRUE, log.p = FALSE)
