Introduction:
The main objective of this study is to determine whether the average waiting time for
patients in IMC unit to receive help after pressing a call bell is different from 6.91 minutes. The
management of IMC unit feels that their patients are not satisfied with their service as they need
to wait for at least 5 minutes to receive help from IMC staff after pressing the call bell. So, they
decided to conduct a study to find out the whether the patient who visits their unit waits for long
time to receive the help. For the purpose of this study, 24 patients are randomly selected from a
normally distributed patient population admitted to the IMC unit.
Frequency Distribution of Patient waiting times:
Totally 24 patients was randomly selected from the IMC patient population. Out of 24
patients, only 4 patients said that they waited for 4 minutes (16.67%) to receive help after
pressing a call bell. 5 patients said that they waited for 5 minutes (20.83%) to receive help after
pressing a call bell. About 15 patients said that they have to wait for at least 7 minutes (62.5%) to
receive help after pressing a call bell. The bar chart showing the distribution of waiting time of
patients at IMC unit is given below:
From the above bar chart, we see that most of the patients wait for at least 7 minutes
(62.5%) to receive help after pressing a call bell. That too, a maximum of 7 patients (29.17%)
waits between 8 minutes and 9 minutes after pressing the call bell
Hypothesis Testing:
Hypothesis testing is defined as a method of making decisions using data from a
scientific study. Selecting appropriate test to test the claim depends up on the sample size and the
information about population standard deviation. If either the population standard deviation is
known or the sample size is large (say, n > 30), then we can use large sample test, that is Z test.
On the other hand, if the sample size is small and the population standard deviation is not known,
then we need to choose any one of the small sample test to test our claim. Two types of error will
occur while performing...
