To find: The type of sample described here. Also, explain if the sample is biased or not.
The type of sample is random and it is unbiased.
Given:
Five students must be chosen by an English teacher to submit book reports to the class. All of the class members' names are written by the teacher on sheets of paper. inserts the parts into a cap. and selects five names without searching.
Explanation:
A subset of a population is chosen at random in a basic random sampling. Each person in the population has an exact equal probability of getting chosen using this sampling technique.
The sample is a random sample since the teacher put the pieces of paper in a hat and picked without looking.
A sample of 55 students is a valid representation of the class as a whole, and it is unbiased.
