Question

A professor had students keep track of the social relations for a week and a number of social directions over the weekend and following the distribution how many students had at least 75 social interactions in the week?

Answer 1

Answer: 12 students

Since we need to find how many students had at least 75 social interactions in the week, we will add up all the frequencies from at least 75 interactions. Looking at the given table, that would be 3, 6, 1, and 2.

Adding them up together and we will get:

$3+6+1+2=12$

Therefore, 12 students had at least 75 social interactions in the week.
