What **types of inferences will we make about population parameters**? A conclusion about the value of a **population parameter**. **We will do** both estimation and testing. … To evaluate the reliability of our **inferences**, **we will** need to know the probability distribution for the statistics **we are** using.

## Q. How can statistics be used to make inferences about the parameter?

**Statistical inference** is based on the laws of probability, and allows analysts to **infer** conclusions about a given population based on results observed through random sampling. … A **parameter** is a number describing a population, such as a percentage or proportion.

## Q. Which helps to make inferences about a population?

Statistical **inference** is the process through which **inferences about a population** are made based on certain statistics calculated from a sample of data drawn from that **population**.

## Q. What is population inference?

**Inference procedures** based on the assumption of a normally distributed sample statistic are referred to as normal theory methods.
