Most analysts focus on the cost of tuition as the way to measure the cost of a college education. but incidentals, such as textbook costs, are rarely considered. a researcher at concordia university wishes to estimate the textbook costs of first-year students at concordia. to do so, she monitored the textbook cost of 250 first-year students and found that their average textbook cost was $300 per semester. identify the sample in the study

The sample is 250 first-year students of the Concordia University

Step-by-step explanation:

When you are making a research you have to take into account two elements: The population and the sample.

The population refers to ALL the individuals that have the characteristic you are investigating, in this case the population of the researcher is the first year students al Concordia University, because he want to estimate the textbook costs for this students because it is not taken into account in the college costs.

The problem is thar if there are a thousand students of first year or more it will be very difficult to make the study because you he will need more resources, more time, and he will have to analyze more information, that's why he takes a SAMPLE that represent the whole population that in this case correspond to 250 first-year students of the Concordia University, this students will represent the population and as a conclusion of his work, he must say that in the costs of college education it must be include other costs such as textbook cost, because in average they have a cost of $300 per semester that must be added to the tuition cost.
