Not sure how to phrase this question but - I want to know who won a contest that lasted over a 5 day period. Craig completed 50 surveys in 40 hours and Ohad completed 29 surveys in 34 hours and Brad completed 15 surveys in 20 hours. I would like the formula and step by step suggestions on the procedure please.

It is not clear to me what the critieria for winning is. How is the winner determined? Most surveys? Most time spent? Least time spent? Largest survey /time rate?

To determine the winner of the contest, we need to understand what criteria will be used to make that determination. Based on the information provided, it is unclear what the specific criterion is. However, we can analyze the data using different criteria to determine the winner.

1. Most surveys completed: In this case, we can compare the number of surveys completed by each participant. Craig completed 50 surveys, Ohad completed 29 surveys, and Brad completed 15 surveys. Therefore, Craig would be the winner if this criterion is used.

2. Most time spent: If the criterion is based on the amount of time spent, we can compare the total hours invested by each participant. Craig spent 40 hours, Ohad spent 34 hours, and Brad spent 20 hours. In this case, Craig would be the winner.

3. Least time spent per survey: If the criterion is based on the efficiency of completing the surveys, we can calculate the time spent per survey for each participant. Craig took an average of 0.8 hours per survey (40 hours / 50 surveys), Ohad took an average of 1.17 hours per survey (34 hours / 29 surveys), and Brad took an average of 1.33 hours per survey (20 hours / 15 surveys). In this scenario, Craig would be the winner as he spent the least time per survey.

4. Largest survey/time rate: If the criterion is based on productivity (largest survey/time rate), we can calculate the number of surveys completed per hour for each participant. Craig completed 1.25 surveys per hour (50 surveys / 40 hours), Ohad completed 0.85 surveys per hour (29 surveys / 34 hours), and Brad completed 0.75 surveys per hour (15 surveys / 20 hours). In this case, Craig would be the winner.

As you can see, the winner can vary depending on the criteria used. If you have additional information or specific criteria in mind, please provide them, and I can assist you further.
