Hello. I studied Econometrics and Statistics in my bachelor and master degrees. Do you want to use p-values and z in order to find which hypothesis is good? Did you use SPSS or Matlab or Eviews to get the histogram?

Hi, I own a statistical consulting business in Australia. I have a Masters degree in Statistics and have lot of experience with hypothesis testing. Few questions: Do you have a average number for less electricity used (i.e. population mean) which can be compared to the sample average? The random chance can be established once there is some number to compare the sample average to. Please do not hesitate to give me a ring on the number mentioned below if you wish to have a chat with me. Regards, -- Anubhav Tewari M: + 61 433 217 720
