Which type of sampling is one where only the first sample unit is selected at random and the remaining units are automatically selected in a definite sequence at equal spacing from one another. It is: Correct Answer Systematic sampling

Explanation

Systematic sampling = In this sample members from a large population are selected according to a random starting point but with a fixed, periodic interval and this interval is called sampling interval(k)

The sampling interval = Population size/sample size = N/n.

Quota sampling = It is non prbbaility version of stratified sampling. In this assembled sample has the same proportions of individuals as the entire population with respect to known characteristics, traits.

Multi stage sampling = It is the taking of samples in stages using smaller and smaller sampling units at each stage. It can be a complex form of cluster sampling.

Area sampling = It is sometimes referred to as block sampling, especially in the United States. It is also a form of cluster sampling. Evaluation. Area sampling is used a great deal in countries where there are no adequate population lists, which are replaced instead by maps.

∴ Option 3 is correct

An operating system uses the Banker’s algorithm for deadlock avoidance when managing the allocation of three resource types X, Y, and Z to three processes P0, P1, and P2. The table given below presents the current system state. Here, the Allocation matrix shows the current number of resources of each type allocated to each process and the Max matrix shows the maximum number of resources of each type required by each process during its execution.   Allocation Max   X Y Z X Y Z P0 0 0 1 8 4 3 P1 3 2 0 6 2 0 P2 2 1 1 3 3 3   There are 3 units of type X, 2 units of type Y and 2 units of type Z still available.
