Please answer all the details of the question

Before researchers launch a survey, they oftentimes "pilot test" it on a smaller scale. This can be useful to assess how much monetary compensation should be given (based on how long the survey takes to complete}. A random sample of 22 university students completed the pilot test survey. Their completion times of the survey (in minutes) are below. Researchers were planning to compensate participants $15 for completing a 20 minute survey. Is there evidence that the survey completion time is signicantly higher than 20 minutes (ie they should give more than $15?)
