Problem: 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.
The staff decides to examine the time it takes for all patients to move through their service process on two successive days (columns A & B of the data set are one sample).
Questions:
1a- Is the variable categorical, discrete or continuous?
1b- What type of sampling did they use?
1c- Summarize these data graphically and using data description techniques.
1d- Is the clinic meeting the national benchmark time? ((Test the hypothesis that the clinic's population mean is less than 90 minutes. Use a 95% confidence level. Assume the variable is normally distributed. State whether the assumptions for the test are met or not)
1a) The variable is a continuous variable
b) The sampling type is population sampling as all the daily population is sampled here
c)
The above shows the summary of the data.
where mean of day 1 = 112.3 and standard deviation = 65.137
where mean of day 2= 101.5 and standard deviation = 67.111
d) for day 1 we can see how the daily mean deviates from the standard 90 min.
assuming normal distribution Z = = 2.296
so the P value = 0.011 so we can say that the clinic is not maintaining the standard for day1
for day 2 if we do the same analysis
assuming normal distribution Z = = 1.149
so the p value is 0.125. So the clinic is matching the standard for day 2
