Best ResponseYou've already chosen the best response.1Good! so they are correct. You will have to look elsewhere. Hints: Step 1: sort the numbers in ascending order. Step 2: verify the values of the minimum and the maximum to see if they are correct. step 3: find the median (of 12 pieces of data) which is the mean (average) of the two middle numbers (the 6th and 7th from the sorted list). Compare with the reported value to look for mistake. Step 4: find the first quartile (Q1) which is the average between the 3rd and 4th numbers from the sorted list. Step 5: find the third quartile (Q3) which is the average between the 9th and 10th numbers from the sorted list. Verify and look for the mistake reported.

Best ResponseYou've already chosen the best response.1I was saying if you found (c), what was the erroneous value, and what is the value you think it should be. I can then confirm to you.
