The standard deviation of a single number, as in this question, is 0.
55.28
The answer will depend on the degree of rounding. To the nearest tenth, (using the IEEE standard for rounding 5s to even) it is 2.4 whereas to the nearest tens it is 0.
8.127 rounded to the nearest half is 8.
The nearest multiple of 10 to 634 is 630. To find the nearest multiple of 10, you need to determine the distance between the number and the nearest multiples of 10. In this case, the distance between 634 and 630 is 4, which is smaller than the distance to 640. Therefore, 630 is the nearest multiple of 10 to 634.
The hundredths place is the 2, with a 5 following, the number would round up to 1.63.
It is 0.7
It is 95.2 (following the IEEE standard).
17000 (Following standard procedure of rounding 5 up)

There are several different measures of average spread: the standard deviation is the most common but average absolute deviation is another possibility. You could also have total ranges or inter-quartile ranges from sets of observations, each one being a measure of spread. Their averages would also be average spreads. You would have to calculate the average spread according to whichever definition you wanted and then round up or down to 2 decimal places (or the nearest hundredths).
It is 17,000 to the nearest thousand
And the following numbers would be...
None of the following.
