Explanation: 

Detailed explanation-1: -Random sampling is the truest form of probability sampling. This type of sampling guarantees that each member of a population has an equal chance of being included in the sample. This type of sampling is ideal for more controlled studies where human bias in the selection of the sample is intolerable.

Detailed explanation-2: -If the number 8 was your first randomly drawn number, what would be the first 5 numbers of your sample? The sampling interval would be nine (2, 700 รท 300 = 9). The first 5 numbers of the sample would be 8, 17, 26, 35 and 44.

Detailed explanation-3: -A basic example of a convenience sampling method is when companies distribute their promotional pamphlets and ask questions at a mall or on a crowded street with randomly selected participants.
