Suppose a researcher is testing a new vaccine on mice to see how well it prevents the flu virus. The lab has 1000 mice available for testing purposes, and each mouse has an identification number. The researcher needs 30 mice to properly run her study of the new flu vaccine. She is considering five different sampling methods. Match the sampling method to each description. a. The researcher uses a computer program to randomly choose 30 of the 1000 mice to use in her study.
b. The researcher chooses the first 30 mice she can reach from the door to the mouse room.
c. The mice are kept in cages on 10 different shelves in the mouse room. The researcher chooses three mice from each shelf.
d. Each cage holds five mice. The researcher randomly chooses six cages to use in her study.
e. The researcher generates a list of identification numbers that has been sorted from smallest to largest. She randomly picks one mouse from the list, and then chooses every fourth mouse until she has 30.

5. stratified

Solution :

Sampling may be defined as the technique of selecting the individual members or the subset of the population to make a statistical inferences and estimates the characteristics of the entire population.

There are several sampling methods. This includes : Systematic sampling, clustered sampling, stratified sampling, quota sampling, judgement sampling, random sampling, convenience sampling and many more.

In the context, the sampling methods for each of the descriptions are :

a). The researcher use computer program to randomly choose a sample of 30 mice of the 1000 mice for using her study

   --- Simple Random

b). The researcher chose the 1st 30 mice as she can reach the door to the mouse room

   --- Convenience sampling

c). The mice those whose are kept in the cages on 10 various shelves in mouse room. The researcher or the experimenter chose the three mice from each shelve.

  Stratified sampling

d). Each of the cage have 5 mice and the researcher randomly chooses 6 cages for her study

Cluster sampling

e). The researcher generates the list of the identification numbers which has been sorted from the smallest to the largest. The researcher randomly picks 1 mouse form the list and selects every 4 mouse until the researcher has 30 mice.

  Systematic sampling

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
