Question
A simple random sample of 500 college students is selected from a students registered at ABC College, and of these 500 students, 100 of them participate in the annual on-campus Spelling Bee. (a) True or False. The proportion of students at ABC College who participate in the Spelling Bee is 20%. True False (b) True or False. The proportion of students at ABC College who participate in the Spelling Bee is likely to be close to 20%, but not equal to 20%. True False In 2012, CBS News reported that "worrying about a math test can quite literally hurt." Before we discuss the validity of this claim, read the short article found on the following website: http://www.cbsnews.com/news/fear-of-math-can-cause-real pain/The article begins "Worrying about a math test can quite literally hurt." This claim alone implies that anyone who worries about a math test could feel pain. Is this claim justified by the results of the article? Explain your answer.Explanation / Answer
Exercise 2:
Since its a random sample from the total population, so the proportion of students at ABC College who participate in the speeling bee is likely to be close to 20%, but not equal to 20%.
(a) False
(b) True

Exercise 3:
No, the claim that anyone who worries about a math test could feel pain is not justified by the results of the article.
Becasue the sample considered only high math anxiety individuals while it is generalised for all the students who worry about the math test which can be due to a lot o other reasons as well like lack of preparation. So, the random sample is not a true representative of the population for which results are published.
