It is 524.5, which is the number halfway between them.
440 as it is the number that is halfway between them, or half of their total.
You put the numbers in order. As there are 8 numbers, and even amount, the median is halfway between the two middle numbers. In this case, that is 61 and 76. The median is therefore 68.5 as it is halfway between them, or the result if you add them and divide by 2.
If there are an odd # of consecutive numbers, they will. If there are an even # of numbers, the mean will be halfway between the two medians.
You can. For example, you can be 100% certain that the value when you roll a die will lie between 1 and 6. Or that the mean of 100 rolls will lie between 1 and 6. It is simply that a 100% CI has little use.
Halfway between 70 and 100 is (70 + 100) ÷ 2 = 85.
The halfway point between 0 and 100 is (0 + 100) ÷ 2 = 50
