A marketing firm wishes to test the effectiveness of the audio/visual presenation of certain information as opposed to the purely audio presentation of information. To this end250 volunteers were given a 10 minute presentation in which the information was presented in an audio/visual format. A second group of 250 volunteers was presented the same information in a purely audio format. Each person in each of the two groups was asked the same 20 questions related to the infomrstion in the presentation. The audio/visual grouo had an average of 10.2 correct responses with a sample standard deviation of 4. The purely audio group had an average of 9.4 correct responses with a standard deviation of 3. The marketing firm believes this means that the audio /visual format leads to better retention of the information.

*NOT A GRADED QUESTION*
What do you think is the best way of sorting out these type of questions. When I'm studying I somehow always mix up negative and positive values or get something off somehow. so that I get one part wrong which leads to getting another part wrong and so on. I understand the concept of elimination and subsition but I can't seem to carry it out very well.
