In order to assess the opinion of students at the University of Minnesota on campus snow removal, a reporter for the student new
spaper interviews the first 12 students he meets who are willing to express their opinion. The method of sampling used is:________.a. a censusb. a cluster samplec. a voluntary response sampled. a convenience samplee. a simple random sample
When a researcher gives more credence to ease when performing its sampling procedure, such sampling process may be referred to as convenience sampling. As described in the scenario above, rather than having to take a Systematic approach at examining the population so as to decide on the best sampling strategy to employ, the reporter of the student newspaper decides to take the easy path towards gathering the opinion of students by interviewing the first 12 students who are willing to give their opinion without any further consideration. Here, the reporter failed to eliminate any sort of possible bias which may be present, as all was sacrificed for the sake of convenience or ease.
Let's first define variables. y: number of shares of $ 10 x: number of shares of $ 12 We write the system of equations: 10x + 12y = 210 y = 2x + 5 Solving the system: x = 75/17 y = 235/17 Answer: she has: 75/17 shares of $ 12 235/17 shares of $ 10
