Answer to Problem 3PT
Option D is the correct option.
Explanation of Solution
Given:
The mean and standard deviation of the values are 4.60 and 1.10
Calculation:
It is given that the mean and standard deviation of the amount of acidity in rainwater is 4.60 and1.10 respectively.
The error in
It is known that mean is not independent of change of origin and scale. Therefore, mean of the corrected pH measurement.
Also, standard deviation is independent of change of origin but not of scale. Therefore, standard deviation of the corrected pH measurement,
Hence, the mean and standard deviation of the corrected pH measurements are 5.64 and 1.32
Option D is the correct option.
Conclusion:
Therefore, option D is the correct option.
