note: we are suppose to answer one question at a time, so i will give u solution for 3rd for rest u have to repost the question again for answers.

3) mean= sum of all observation / total number of observation

12 + 6+ 11 + 12 + 5 + 0 + 2 + 7 + 8 + 7 + 6 + 3 + 12 + 12=103

total observation = 14

mean = 103/14= 7.35
