A random sample of students at North High School were polled on whether they prefer a 15-minute break between classes in the mor
ning or in the afternoon. The results are shown in the frequency table. A 4-column table with 4 rows. The first column has no label with entries 10th, 11th, 12th, total. The second column is labeled morning with entries 21, 16, 19, 56. The third column is labeled afternoon with entries 17, 25, 20, 62. The fourth column is labeled total with entries 38, 41, 39, 118.
What is the joint relative frequency for 11th graders who want the break in the afternoon? Round to the nearest percent
Answer by JKismyhusbandbae: A bar graph because they are used a lot to compare the sizes of categories and it would show the countries different populations telephones per every 1000 people.
This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.
