Question 4

A simple random sample of 900 students from a college with student population 10,000 is taken to estimate the percentage of commuters. The result is 378 students commute. Thus, we can infer that about [A]% of the student population commute. This is inferential statistics where we infer some parameter of the population from the statistics of the population.

Using the bootstrap method, the SD of the box is estimated to be 0.5 by using the short-cut formula.

The SE for percentage is 1.7%. Double check this number to make sure you know how to calculate

Statistics that allow for inferences or estimates about the population. Inferential statistics enable analysts come to conclusions about the population based on sample data. Inferential statistics cover the basics of inferential statistics, all kinds of hypotheses tests and their confidence intervals, design of experiments, and statistical power and errors. It also includes point estimation techniques, limit theorems, sampling distributions, approximations, and bounds. Correlation, regression, and association are also covered under inferential statistics to infer relationships between variables.
