Please tell me if my answers are right.

Suppose that a series of measurements have shown that the mean mass of an object is 122.4g with a standard deviation of 1.3g. How many significant figures are justified in the mean and how would you report the most probably mass of the object?

a.)Number of significant figures justified in mean value:

b.) Most probable mass of the object:

for a I got 3

for b I got 94.2
