(a) Develop an appropriate Hypothesis Test at 0.10 significance level to validate DLS Management’s claim. You may adopt either critical or p value approach with the help of outputs from Excel Data Analysis tool. However, you are required to show all the test steps. Explain the type of Hypothesis Test Error that may occur in your test conclusion, the consequence of this error, and how the probability of its occurrence can be reduced.

(b) The Taskforce wants to know whether there are differences in various hospitals’ abilities to treat the Covid-Pi patients. It collected a sample each from a Public, Community and Private Hospital on their patients’ recovery periods in days as shown in the GBA Data file (see worksheet ‘Patient Recovery’). Apply an appropriate test at 0.05 significant level using p value approach with the outputs from Excel Data Analysis tool. You must show all the test steps. 

(c) The Taskforce consults you on the approach used in Q1(b) and Q2(a). Discuss three (3) statistical concerns you have (excludes the issue on type of Test Error in Question 2(a)). If you can start the process again from data collection to analysis, explain qualitatively how you would conduct the study.
