Question

What percentage of students has an arm span of at least 170 cm in the given stemplot of arm spans for 44 students?

Option a: 32%
Option b: 45%
Option c: 55%
Option d: 41%

Answer 1

Without the specific stemplot data, the exact percentage of students with an arm span of at least 170 cm can't be calculated. However, if provided with the stemplot, one would count the number of students with an arm span of 170 cm or above, divide by the total number of students, and multiply by 100.

Step-by-step explanation:

To determine the percentage of students with an arm span of at least 170 cm from a stemplot, we need specific data from that stemplot. Since the data provided in other examples does not directly relate to the question asked by the student, we cannot calculate the exact percentage without the correct stemplot data. However, I can guide you on how to find the answer once you have the appropriate stemplot.

Here's a general step-by-step explanation:

1. Examine the stemplot and identify the range that represents arm spans of 170 cm or more.
2. Count the number of entries (students) that have an arm span of 170 cm or above.
3. Divide the count by the total number of students in the study, which is given as 44, then multiply by 100 to get the percentage.

For example, if there are 14 students with an arm span of at least 170 cm, the calculation would be (14/44) * 100, which equals approximately 31.82%. You would then compare this value to the options provided to find the closest match, ensuring to round correctly.
