Hello there, I was just wondering if someone could help me on these problem
Now that she has some descriptive information on her sample, your colleague wants to discover how well her sample represents the population from which it was selected. She tells you that the population size was 500 and that she used probability sampling procedures to select and survey 50 people.
1. What would have happened if she had selected a different sample of 50 people? What would have changed.
2. Will she be able to use her sample statistic to estimate the true population parameter? Why or why not?
3. Will she be able to use her sample statistic to state with 100% accuracy the actual population parameter? Why or why not? Thanks
