I WILL GIVE YOU 10 POINTS FOR EACH QUESTION. I WILL GIVE BRAINIEST IF YOU ANSWER ALL CORRECTLY.
Question 1(Worth 20 points)
The number of miles Sergio biked per day is displayed in the line plot.
A horizontal line labeled Number of Miles that starts at 5 with tick marks every one-half unit up to 10. There is one dot above 7, 8, 8 and a half, 9, and 9 and a half. There are two dots above 7 and a half. There are four dots above 6. There are five dots above 5 and 5 and a half. The graph is labeled Miles Biked Per Day.
Which of the following describes the spread and distribution of the data represented?
The data is symmetric, with a range of 4.5. This might be because Sergio has a favorite path that is 7 miles long.
The data is skewed, with a range of 4.5. This might be because Sergio has a hard time riding further than 6 miles.
The data is bimodal, with a range of 10. This might be because Sergio has two paths that he rides the most frequently at 6 and 9 miles each.
The data is symmetric, with a range of 5. This might be because Sergio is always able to ride more than 7 miles each time.
Question 2(Worth 20 points)
The heights of 11 plants, in inches, are listed.
14, 15, 16, 16, 17, 17, 17, 18, 18, 19, 22
If another plant with a height of 14 inches is added to the data, how would the range be impacted?
The range would decrease to 8 inches.
The range would stay the same value of 8 inches.
The range would increase to 17 inches.
The range would stay the same value of 18 inches.
Question 3( Worth 20 points)
The box plot displays the number of push-ups completed by 9 students in a PE class.
A box plot uses a number line from 9 to 45 with tick marks every 2 units. The box extends from 17.5 to 40.5 on the number line. A line in the box is at 30. The lines outside the box end at 10 and 42. The graph is titled Push-Ups In PE and the line is labeled Number of Push-Ups.
Which of the following represents the value of the lower quartile of the data?
42
40.5
17.5
10
Question 4( Worth 20 points)
A student's grades in a history class are shown in the histogram.
The histogram is titled Grades in History Class, and the x-axis is labeled Grade Earned. The x-axis has intervals of 41 to 50, 51 to 60, 61 to 70, 71 to 80, 81 to 90, and 91 to 100. The y-axis is labeled Frequency and starts at 0 with tick marks every one unit up to 10. There is a shaded bar above 41 to 50 that stops at 2, above 51 to 60 that stops at 1, above 61 to 70 that stops at 1, above 71 to 80 that stops at 4, above 81 to 90 that stops at 7, and above 91 to 100 that stops at 6.
Which statement best describes the spread and distribution of the data?
The data is almost symmetric, with a maximum range of 59. This might be because the topic is easily understood by the students.
The data is skewed, with a maximum range of 59. This might be because the teacher offered extra credit, and most of the students did that to increase their grades above 70.
The data is bimodal, with a maximum range of 59. This might be because students either did not understand and earned less than 51, or they knew the topic well and earned higher than 90.
The data is symmetric, with a maximum range of 59. This might be because the topic was very difficult for the students and most of them earned lower grades.
Question 5(Worth 2 points)
The data collected on the number of points scored in a basketball season are represented in the box plot.
A box plot uses a number line from 13 to 33 with tick marks every one-half unit. The box extends from 16 to 31 on the number line. A line in the box is at 24. The lines outside the box end at 14 and 32. The graph is titled Number of Points, and the line is labeled Points Scored in Basketball.
