Question

Part 2

The Striving for Perfection Urgent Care Center feels that its patients wait time is too long.
The staff has noticed that increasing numbers of people are waiting longer in the waiting room.
The national benchmark performance is 90 minutes or less from the time the customer arrives
to the time the customer is treated and discharged.

Part II
The staff thought that the type of service might have an impact on the time it took for the patient
to go through the entire process. So they collected a new set of data on one day showing the
elapsed time and a code for four different types of service (columns D and E of the data tab).
Answer Questions 1 to 5 for these data (number them 8 to 12),
considering that there are two variables this time. (28 points)

Question 1 (2 points): What type of variable did they choose to examine? Qualitative or quantitative?
Question 2 (2 points): Is the variable categorical, discrete or continuous?
Question 3 (2 points): How many observations did they collect?
Question 4 (2 points): What type of sampling did they use?
	Random, systematic, stratified, clustered, or convenience.
Question 5 (20 points): Summarize these data graphically and using data description techlniques.

Answer 1

Answer# 1) One variable is type of service which is coded from 1 to 4 This is called qualitative data, as it tells about the type of service Answer# 3) There are total 44 rows shown in the dataset shared, hence total number of observations is 44 Second variable is: time elapsed. This is a quantitative data So : Type of service: qualitative and time elapsed: quantitative Answer# 4) The sample here seems to be convenience sampling the data is collected on a single day for all the patients who entered in. There waiting time and service type preferred are taken not of this type of method of sampling is called convenience sampling Answer# 2) Type of service: is cateogrical variable, the categories of four service types in it are labeled as coded numbers from1 to 4 These codes help to categorize the data Time elapsed: is generally a continuous variable, but observing the dataset provided, one can note the time here has been provided as whole numbers, hence for this experiment time has been considered to be discrete So, type of service: categorical, and time elapsed: discrete
