Productivity problem

1.  An electrical equipment manufacturing company manufacturers AC motors, DC motors & transformers.   During the month of December the production of these items in Rupee terms has been respectively, Rs.140 million, Rs.250 million and Rs.90 million. The   inputs   of human   resources,   capital materials and power have been given below:

		Product
	AC	DC	Transformers
Human	14	23	12
Capital	28	81	14
Materials	72	108	24
Power	9	20	10

     1)    What are the total productivities of each of the three products?   

     2)    What are the partial productivities of each of the inputs?

     3)    What are the partial productivities of each of the three products? 

It is one easy and basic problem which is asked in exams frequently.

Group Work on Sample Size Calculation

1.      The mean birth weight (SD) of newborn is observed to be 2.25(0.4) kg in pregnant women belonging to low socioeconomic group. A study is to be carried out to determine whether nutritional supplementation would increase the birth weight of newborn. It is planned to include two groups of pregnant woman - one without supplementation (control group) and the other with supplementation (test group). Calculate the size of each group.

2.      The cure rate of a drug in a disease is 20%. It is claimed yoga is better than the drug and a trial is to be conducted find out the truth. It is decided that a even 10% increase in cure rate would be clinically important. The alpha and beta were set at 0.1 and 0.1. The results will be analysed using Chi Square test. How many patients would be required for the trial?

3.      The mean(SD) hospital stay of patients after a conventional surgical procedure (CP) is 12.3(4.8) days. A modified procedure(MP) is to be tried to reduce the stay. Two groups of patients will be undergoing either CP or MP. Their hospital stay will be compared using unpaired t test at p<0.05 with power of 90%. The minimum important difference is expected to be 3.Calculate the sample size for each group.

Employee Satisfaction Survey – As a Retention tool and a Hygiene factor

 What is employee engagement exactly? Alpha Measure defines employee engagement as the level of commitment and involvement an employee has towards their organization and its values.

The primary behaviors of engaged employees are speaking positively about the organization to coworkers, potential employees and customers, having a strong desire to be a member of the organization, and exerting extra effort to contribute to the organization’s success.
