Your team needs to decide how to measure the effectiveness of
this measure. You think the best way would be to compute the values
of the sensitivity, specificity and predictive value. Show your
work and provide an interpretation of these measures.
On the basis of your results, is this an effective measure? Why
or why not?
Once you assess the effectiveness of this measure, and your
team feels confident that this is an appropriate measure to use,
the Health Administrator of the Unit asks your team to examine the
odds of patients being readmitted for those who were administered
at least 3 drugs. Calculate the odds ratio and explain this finding
to your administrator.
The main trial is conducted and involves a total of 200
patients. Patients are enrolled and randomized to receive either
the experimental medication or the placebo. The data shown below
are data collected at the end of the study after 6 months on the
assigned treatment.

Please answer the problem below
Subu Motors has total capital of $200 million, consisting of 40%
debt (costing 5% before taxes) and 60% equity (costing 9%). Subu’s
