The president of the university plans a speech to an alumni group. He plans to talk about the proportion of students who responded in the survey that they are the first in their family to attend college, but the first draft of his speech treats that proportion as the actual proportion of current students who are the first in their families to attend college. Explain to the president the difference between the proportion of respondents who are first attenders and the proportion of the entire student body that are first attenders. Use appropriate statistics terminology.

Proportions of students who were surveyed form a sample from the total number or population of  students

Explanation:

Proportion of respondents is a sample of students taken from an entire population or the entire student body choosen to represent the entire student pody. The proportion of respondents who said that they are first attenders will differ from actual proportion of 1st attenders from entire student body by some amount called standard deviation. If another group pf respondents is investigated, it may or may not have same proportion of 1st attenders. the extent to which this other group of respondents will have same proportion of 1st attenders will be given by a parameter called confidence interval.
