A study was conducted among college freshmen concerning favorite fruits and test scores. Students were asked their favorite fruit and given their selection as a snack directly before an exam.
Evidence has shown that individuals who consume higher amounts of berries and citrus fruits are more likely to score higher on an exam than those that consume more starchy fruits such as bananas and apples. This could be due to the research surrounding berries as high powered ‘brain food’, and the instances of starchy fruits inducing sleepiness.
The pie chart shows the percentage of fruits preferred by college freshmen at Trinity Community College. Which of the following statements is true based on the pie chart and explanation?
Around 30% of the students are expected to score higher on the exam than the other 70%.
This answer is correct. According to the explanation, students who consume citrus and berries are more likely to score higher on exams. 18% of students selected oranges and 11% selected strawberries, which combined totals 29%, or about 30% of students would be expected to score higher on their exams.
Around 70% of the students are expected to score higher on the exam than the other 30%.
This answer is incorrect. According to the explanation, students who consume starchy fruits such as bananas and apples are more likely to score lower than their counterparts who selected oranges or strawberries. About 30% of students selected oranges and strawberries, and about 70% selected apples, bananas, and ‘other’.
More students chose citrus and berries as their favorite fruit, likely in an effort to score higher on their exams.
This answer is incorrect. Less students selected citrus and berries as their favorite fruits than the other choices, and additionally, there is no context given to suggest that the students made their selection with the information regarding test scores.
Apples are the most highly preferred fruit and therefore those students who selected apples will score the highest.
This answer is incorrect. While apples are the most preferred fruit, the evidence suggests these students will score lower than the students who selected
