5. The box-and-whisker plots show data for the test scores of four groups of students in the same class.
Which plot represents a group with a median grade below 65?
6. The table below shows the amount of time several students spent watching TV during one week a their test grades.
7. You want to determine the average age when people got their driver's license. You want to collect data from a random sample of at least 400 people. Which of these would be the most valid method for collecting data?
• Survey all students coming in and out of your school cafeteria.
• Survey an equal number of students of driving age, teachers, parents, and grandparents.
• Survey the residents in a retirement community.
O Survey a group of elementary school students.
8. A researcher captured, tagged, and released 75 rabbits in a meadow. She later captured 30 rabbits, and found that 10 of them were tagged. Based on this information, what is a reasonable estimate for the rabbit population in the meadow?
0 225
0 25
O 255
0 525
9. Brenda is the owner of Brenda's Hair Salon. She produced the following graph to show that her customers are more satisfied than customers of two nearby salons owned by Nancy and Tammy. Which statement best describes why the graph is misleading?
1. I cannot make plots on this platform. However, I can guide you. First, arrange the data in ascending order: 56, 57, 57, 57, 58, 58, 59, 61, 64, 64. Plot the data points on a straight line while also plotting the corresponding points on the x-axis. Connect the points in the order that they appear.
2. Mean: (19 + 19 + 14 + 14 + 16 + 19 + 19 + 16 + 16 + 15 + 17 + 16 + 17 + 16 + 15 + 14 + 15 + 15 + 17 + 14 + 16 + 15)/22 = 16.4
Median: Arrange the data in ascending order and find the middle value. If there are two middle values, find their average. In this case, the two middle values are 16 and 16. (16+16)/2 = 16
Mode: 16 (since it appears the most number of times)
3. Without frequency distribution table options, I cannot determine the answer to this question. Please provide the options.
4. The data represented by the stem-and-leaf plot is 37, 38, 39, 41, 43, 47, 52, 54
5. Without the box-and-whisker plot options, I cannot determine the answer to this question. Please provide the options.
6. Without the table of student TV time and test grades, I cannot answer this question. Please provide the table.
7. The most valid method for collecting data in this case is to survey an equal number of students of driving age, teachers, parents, and grandparents. This will give a more representative sample of the population.
8. If 10 out of 30 captured rabbits were tagged, that represents 1/3 of the captured rabbits. So, the tagged rabbits (75) would comprise about 1/3 of the total population. To find the estimated total population, you would multiply 75 by 3. 75 * 3 = 225. Therefore, a reasonable estimate for the rabbit population in the meadow is 225.
9. Without seeing the graph or having descriptions of the graph, I cannot determine why the graph is misleading. Please provide either the graph or descriptions of it.
