The resistance of the sample is 
Explanation:
The relationship between resistance of a material and temperature is given by the equation
where
is the resistance at the temperature 
is the temperature coefficient of resistance
For the sample of nickel in this problem, we have:
when the temperature is 
While the temperature coefficient of resistance of nickel is
Therefore, the resistance of the sample when its temperature is
is
