OVERVIEW:
Sampling distribution example problem | Probability and Statistics | Khan Academy is a free educational video by Khan Academy.It helps students in grades 9,10,11,12 practice the following standards HSS.MD.A.1,HSS.MD.A.3,HSS.MD.A.4.
This page not only allows students and teachers view Sampling distribution example problem | Probability and Statistics | Khan Academy but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.
1. HSS.MD.A.1 : Define a random variable for a quantity of interest by assigning a numerical value to each event in a sample space; graph the corresponding probability distribution using the same graphical displays as for data distributions..
2. HSS.MD.A.3 : Develop a probability distribution for a random variable defined for a sample space in which theoretical probabilities can be calculated; find the expected value. For example, find the theoretical probability distribution for the number of correct answers obtained by guessing on all five questions of a multiple-choice test where each question has four choices, and find the expected grade under various grading schemes..
3. HSS.MD.A.4 : Develop a probability distribution for a random variable defined for a sample space in which probabilities are assigned empirically; find the expected value. For example, find a current data distribution on the number of TV sets per household in the United States, and calculate the expected number of sets per household. How many TV sets would you expect to find in 100 randomly selected households?.
