here. In this problem we have to find the main division about the median for the following data. First of all, we will find the median. So in order to find the median, we will arrange the given data in ascending order. We have 10 comma 11, comma 11 comment wells go amantadine, coma 14 comma 16 comma 16 comma 17, Coma 17, Coma 18. Here we have n. s. equals to 12, Which is even so median is the average of 16 7 observation. Therefore we get meeting And which is equals two, 13 Lus 14.2. It would be equal to 13.5. Now, we will find the absolute value of the deviation from the mean that is X I minus median. Uh huh. Here we have meeting is 13.5 so X one minus median would be 10 minus 13.5 since we are finding the absolute value of the derivative. So we will drop the minus sign here, navigate Then -13.5 is 3.5 plus 11 -13.5 years, 2.5 Plus 11 -13.5 years, 2.5 Yes, 12 -13.5 is 1.5 plus 13 -13.5. Plus. 13 -13.5. Plus. 14 -13.5. Yes. 16 -13.5 years, 2.5 Yes. 16 -13.5 is 2.5 Plus 17 -13 17 -13.5. 3.5 Plus 17 -13.5 is 3.5 bless 18 -13.5 is 4.5 It would be equals to 28. Now we know that main division about meeting is equal to van a poner en sigma, Where I goes from 1 to N derivative from the mean main aviation about median is equal to one a 10.12 into 28. It would be equals two, 2.33. Therefore, we get the main division. About million Is equals to 2.33.
