Answer:
The question is incomplete as the boxes of description is not given but the missing part is attached in the image-
Brain and spinal cord have a membranous covering made up of three layers, altogether known as meninges. These 3 layers are known as the Dura mater follows by the arachnoid mater and inner layer is the pia mater.
The description of the different layers are as follows-
1. Dura mater is the most superficial layer of the meninges. The superior sagittal sinus is present within this dura mater.
It creates tough inward folds that distinguished the cerebral hemispheres. Lines the inner side of the cranium in the skull.
2. Arachnoid mater is the middle layer present under the dura mater layer that surrounds the subarachnoid space. This layer is present Immediately deep to the subdural space.
3. Pia mater makes the deepest layer that follows the contours of the surface of the brain.
Answer: They must be randomly chosen, meaning that each member of the larger population has an equal chance of being chosen. They must be large enough so as not to skew the results. The optimal size of the sample group depends on the precise degree of confidence required for making an inference. Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample.
Hope this helps... Stay safe and have a great day/night!!! :D
