A study is conducted to determine how playing a sport affects a student's overall health and well-being. The study includes 100 high school students on various sports teams. The study includes a survey composed of 5 statements to which students respond on a scale
of 1-5. A response of 5 indicates strong agreement with the statement and a response of 1 indicates strong disagreement with the
statement. The results of the statement, "Participating in a sport helps to improve a person's ability to prioritize his or her free time."
shows an average response score of 3.2 and a standard deviation of 1.2. One conclusion in the report of the study states that
participation in sports markedly improves a student's ability to make good use of free time.
Which statements regarding the report are true?
Select each correct answer.
The report of the study should state that there is a strong correlation between participation in sports and ability to prioritize
free time rather than make broad conclusion.
The report does not accurately interpret the result of the statement regarding prioritizing free time.
The study is biased since the survey includes only students playing a sport so the report should not be considered accurate.
The report accurately states the results because a mean score of 3.2 is greater than the predicted average of 3 on the
statement regarding prioritizing free time.
The report should be considered accurate only if the sample is a stratified sample of students playing sports.
