Briefly discuss the various organizational forms of Public Sector Enterprises.

Suppose you try a regimen A on 1000 subjects and regimen B on 1600 subjects. Results of the trial show that efficacies of regimen A and B are 76% and 82% respectively. Suppose doctor determines 4% as superiority margin. Can you consider regimen B as superior to regimen A. 

Creatinine excretion is a parameter of kidney function. Generally speaking, lower values indicate better health. This depends on body weight. A researcher conducted a study on creatinine excretion in test group and control group to find the efficacy of a new drug. The subjects were randomly divided. He included 100 subjects in each group but for this exercise consider only 10 subjects in each group. The data obtained on creatinine level in these 10 subjects are as follows:

Do you think that creatinine excretion was really lower in the test group on average?  

Explain design and analysis of data of case control study in detail

Obtain sample size for the following given information: 

δ=0.04,  π₁ = 0.72,  π₂ =0.84, α =0.01, β =0.25

If D+ and D ̶ denote presence and absence, respectively, of a disease and T+ and T ̶ denote test result as positive and negative, respectively, then on the basis of the following information:  

Find: (i) sensitivity (ii) specificity (iii) positive and negative predictive values.

In a parallel-line assay, total 18 guinea pigs, 4 guinea pigs each from 3 different breeds were selected and classified into 4 groups for each breed. Two groups were administered with two doses of the standard preparation and remaining two groups with two doses of the test preparation. The responses of these doses are recorded in the following table:  

 (i) Determine the dose-response regression models for both preparations.
(ii) Test whether the dose-response curves of both preparations are linear and parallel to each other or not.
(iii) Interpret whether the relative potency and its confidence interval can be computed or not. 

What is Just-in-Time production? How does it differ from Manufacturing Resource Planning (MRP)? What is MRP-JIT system? 

Hip Replacements, Inc. has a master production schedule for its newest model, as shown below, a setup cost of `50, a holding cost per week of `2, a beginning inventory of 0, and a lead time of 1 week. What are the costs of using lot-for-lot for this l0-week period? 

Discuss various qualitative methods of forecasting.

Draw a network diagram for the activities given below and determine the critical path.

Discuss the importance of market and demand analysis in project management.  

What is project management? Discuss the components of project feasibility analysis with suitable examples.

A has two ammunition stores, one of which is twice as valuable as the other. B is an attacker who can destroy an undefended store, but he can only attack one of them. A can successfully defend only one of them. A learns that B is about to attack one of the stores but does not know which. What should he do? 

What constitutes inventory ordering costs, carrying costs and stock-out costs? Explain the behaviour and relationship of these costs. 

A company has three plants at locations A, B, and C, which supply to a warehouse located at D, E, F, G, and H. monthly plant capacities are 800, 500 and 900 units, respectively. Monthly warehouse requirements are 400, 400, 500, 400 and 800 units. Unit transportation costs (in `) are given below. Determine an optimum distribution for the company in order to minimize the total transportation cost.
