random selection
census
sample
voluntary response

question #2
a university conducted a study to determine if men or women are more likely to major in physical therapy. it is known that 58
college population are women. 65% of their physical therapy majors are women.
is there statistical evidence to support that women are more likely to major in physical therapy than men?
yes, because the results are likely to occur by chance.
yes, because the results are unlikely to occur by chance.
no, because the results are unlikely to occur by chance.
no, because the results are likely to occur by chance.

Explanation:

Question #1

A census involves collecting data from every member of a population. In this case, choosing every student at a school means data is collected from the entire population (all students in the school). Random selection would involve a random - based method to pick some students. A sample is a subset of the population. Voluntary response is when individuals choose to participate on their own.

If 58% of the college population are women, and 65% of physical therapy majors are women. Since 65%>58%, this difference is not likely to be just due to chance. Statistical evidence for a claim (here that women are more likely to major in physical therapy) is supported when the observed result (higher proportion of women in physical - therapy majors compared to the general college population) is unlikely to occur by chance.

Census
