Graphs must be appropriately titled and should refer to the

Units should always be included when referring to numerical
values.

When making a comparison you must use comparative language,
such as “greater than”, “less than”, or “about the same as.”

Ensure that all graphs and
tables appear on one page and are not split across two pages.

Type all mathematical
calculations when directed to compute an answer ‘by-hand.’

Pictures of actual
handwritten work are not accepted on this assignment.

When writing mathematical expressions into your document you
may use either an equation editor or common shortcuts such as: can be written as
sqrt(x), can be written as p-hat, can be written as x-bar.

Problem 1: Moviepass/AMC A-List

Moviepass
is a subscription service that allows users to see one movie per day at select
theaters. AMC Theatres released their
own movie subscription service called A-List to compete with Moviepass which
allows users to see up to three movies per a week. Raw data was collected from one user who
purchased an annual Moviepass subscription in January 2018 and subscription to
A-List from November 2018 until August of 2019.
The dataset found in our StatCrunch Group presents 257 movies seen along
with other variables describing each movie. The data set is called “Moviepass/AMC
A-List.”

a)
Use StatCrunch to create a one-way table for the variable “Month” using both counts and
percentages. Select Stat à Tables à Frequency. Select “Month”
in the Select Column(s) box, and select both ‘Frequency’ and ‘Percent of total’
in the Statistic(s) box by holding down the Ctrl Key (Command Key on Macs) when
making these selections. Copy your table into your document and then manually round
the values in the ‘Percent of total” column to two decimal places in the
StatCrunch table that you have copied into your document.

b)
Interpret your findings from the table in 1(a) by
identifying the least and most frequented month by percent of total. Use complete sentences with context and
include the month and percentage in the sentences.

c)
Use StatCrunch to generate a two-way table for the variables
“Month” and “Subscription”. Go to Stat à Tables à Contingency à With Data (since you have the raw data
in StatCrunch). Select “Month” as your row variable and “Subscription” as your column
variable. In the display box, select
only Percent of Total. Lastly,
unclick (or deselect) “Chi-Square test for independence” since it is
highlighted by default by holding the Ctrl key and clicking on it. Copy your table into your document.
