Answer :

Answer:

Since there are 320 students, and Preston expects 0.5% of them to be from Australia, the expected count of students from Australia is 0.005 (320) =1.6

The expected count students from Australia is 1.6.

Step-by-step explanation:

Lanuel

The expected count of students from Australia in Preston's group is equal to 1.6.

What is a goodness-of-fit test?

A goodness-of-fit test can be defined as a statistical tool that is used to test if sample data fits into a set of observations or distribution from a given population.

This ultimately implies that, a goodness-of-fit test helps to determine whether on not sample data represents the data that are expected in an actual population.

Given the followin data:

Popuation = 320 students.

Expected percent (Preston's group) = 0.5% = 0.005.

Expect count = 0.005 × 320

Expect count = 1.6.
