Question

the dot plot shows the number of hours spent studying for an assessment. based on the data distribution, which of the following statements is correct? (1 point) there are more people who studied for more than three hours than the number of students who studied for less than three hours. the minimum number of hours spent studying is one hour. the maximum number of hours spent studying is eight hours. more students studied three hours or less than the number of students who studied four hours or more

Explanation:

Step1: Count students studying less than three hours

Count dots at \(0\), \(1\), \(2\) hours. There are \(2 + 2+2 = 6\) dots.

Step2: Count students studying more than three hours

Count dots at \(4\), \(5\), \(6\), \(7\) hours. There are \(1+1 + 2+1=5\) dots.

Step3: Analyze each option

  • Option "The minimum number of hours spent studying is one hour": From the dot - plot, the minimum is \(0\) hours. So this is wrong.
  • Option "The maximum number of hours spent studying is eight hours": From the dot - plot, the maximum is \(7\) hours. So this is wrong.
  • Option "More students studied three hours or less than the number of students who studied four hours or more": Students studying three hours or less (\(0\), \(1\), \(2\), \(3\) hours) have \(2 + 2+2 + 1=7\) dots. Students studying four hours or more (\(4\), \(5\), \(6\), \(7\)) have \(1+1 + 2+1 = 5\) dots. \(7>5\), so this is correct.
  • Option "There are more people who studied for more than three hours than studied for less than three hours": As calculated in Step1 (\(6\)) and Step2 (\(5\)), \(6>5\), so this is wrong.

Answer:

More students studied three hours or less than the number of students who studied four hours or more.
