Answer 1

To find the percentage of students with an arm span of at least 170 cm, count the number of students meeting this criterion (20), divide by the total number of students (44), and multiply by 100%. The percentage is approximately 45.45%, so the correct answer is 45%.

Step-by-step explanation:

The question provided is about calculating the percentage of students with an arm span of at least 170 cm based on a given stemplot. To determine this percentage, we first need to count the number of students with an arm span of 170 cm or more. According to the data provided, there are 170, 170, 171, 173, 175, 176, 179, 179, 180, 180, 181, 182, 182, 183, 186, 186, 189, 190, 192, 202. This makes a total of 20 students. Since there are 44 students in total, the calculation for the percentage is (20/44) × 100%, which equals approximately 45.45%. Therefore, the correct answer is 45%, and this is the percentage of students with an arm span of 170 cm or more.
