Question

A 2016 Pew Research poll estimated the proportion of people supporting each presidential candidate in the fall election. They based their estimates on telephone interviews of 2, 010 adults living in all 50 U.S. states They asked each participant which presidential and vice presidential candidate they support, and used that data to calculate the proportions. What is the statistic in this experiment? Select the correct answer below: a.The candidate each participant supports. b.The number of people Pew Research interviews. c.The number of people in the United States. d.The proportions of participants who support each presidential candidate. e.The proportions of U.S. adults who support each presidential candidate.

Answer 1

The proportions of participants who support each presidential candidate.

Explanation

Answer 2

option A- The candidate each participant supports.

Step-by-step explanation: the question asks about the 'statistics in the experiment', meaning the major factor or say the most important data to be considered to achieve the desired aim/result of the experiment.

From the question, the aim/result of the Research poll was to get 'the PROPORTION of people supporting each presidential candidate in the fall election'. Note that to find 'PROPORTION', you must first find the individual values and then compare them. That's what 'PROPORTION' is all about - comparing number of things or people.

So to achieve this, the most important data-'statistics' in this experiment is knowing the candidate each participant supports.

For example, if there are 5 presidential candidates: Mr A, B, C, D & E and after interviewing 2,010 adults, you find out that:

134 people supports Mr A;

268 people supports Mr B;

402 people supports Mr C;

536 people supports Mr D and

670 people supports Mr E.

Now because you know the candidate each participant supports, you can now derive the 'PROPORTION' of people supporting each candidate which is 134:268:402:536:670. NB: you have to always leave your answer in its lowest term, so the proprtion here is 1:2:3:4:5.
