The population of students has an average ACT score of 22 with standard deviation of 4. What is the expected value of the average of samples taken from this population?
Homework Answers
Hello SIr/Mam
YOUR REQUIRED ANSWER IS 22
Given that the average population ACT score is 22 with S.D. 4.
Now, the expected value of the average of samples taken from the population always tends to converge to the population average, i.e. 22.
Hence, the expected value of average of samples taken from the given population is 22.
I hope this solves your doubt.
Feel free to comment if you still have any query or need something else. I'll help asap.
Do give a thumbs up if you find this helpful.

Suppose that a very large population of students has taken this same test on the internet. Their mean score was 7 and their population standard deviation was 4. Assume that there are 49 students in our statistics class and that these students can be thought of as a random sample from the same large population of students who took the statistics quiz online. Suppose that the mean quiz score for our class is 9. Now imagine that we draw many...
