Julie is conducting a survey and asked 25 people to respond on a 1 to 15 scale to questions. A total of 19 people returned the survey and she calculated the results. She finds that for one particular question the mean was 11.2, the range was 11, and the median was 13. Three days later four more surveys were turned in and they responded to the same question with {10, 14, 15, 1}. To the nearest tenth what is the new mean?

penguin: Sitting by the river, Dreaming through my reflection, I wonder what has happened. What has caused this distance? We used to be together, Cuddling close to each other. What came between our beautiful love? I don't know, though I wish to. I can see you now, not alone You're holding a hand that's not mine Where am I? Why not next to you? Why am I away? I don't understand. You're smiling to the fullest. I am not the one making you happy. You are glancing at someone else. Why is it not me? Seeing you after such a long time, My heart sighs again. Something inside me growls loud 'Cause now your hand runs through her hair. I stand some distance well away, But the surroundings disappear. When I look at you, I feel lost inside I wish you back, my angel. There you are, holding her hand, And I am lost, trying to understand. I want you back, I really do, Just to hold your hand And walk with you.
