Final answer:
To find the answers, you need the data regarding the number of connections for each student on both social networking apps. Once you have the data, you can calculate the average number of connections, determine the number of students with more than 500 connections, find the app with the highest average connections, and calculate the range of the number of connections.
Step-by-step explanation:
In order to answer the questions, we need the data regarding the number of connections for each student on both social networking apps. The given information in the question does not provide this data, so we cannot provide specific answers. However, I can explain how to find the answers once you have the required data.
To find the average number of connections (A), you would add up the number of connections for all the students and then divide it by the total number of students. To find how many students have more than 500 connections (B), you would count the number of students whose number of connections is greater than 500. To determine which app has the highest average connections (C), you would calculate the average number of connections for each app separately and compare them. Finally, to find the range of the number of connections (D), you would subtract the smallest number of connections from the largest number of connections.
