After going over the attendance data, i have learned that twenty percent of our students are calling in sick every day, and it would be good to do something to stop this problem.
which appeal is the speaker using in the sentence?
ethos, an appeal based on the speaker’s character
logos, an appeal based on logic and reason
pathos, an appeal based on the audiences’ emotion
eros, an appeal based on love

Actually, almost in every persuasive speech (especially in those where the speaker tries to encourage the audience to accept his position\ particular viewpoint on an issue) the orator uses pathos, appealing based on the audience's’ emotion. But in this statement I clearly see that the author shares his experience and represents his research as a fact, demonstrating his will to resolve this problem. So it is definitely logos, an appeal based on logic and reason. There is no mention of hard feelings or character's traits so the other options are extra.
