Measured. The mean and standard deviation of the values are 4.8 and 1.2 respectively. When the pH meter was recalibrated back at the laboratory, it was found to be in error. The error can be corrected by adding 0.3 pH units to all of the values and then multiply the result by 1.4. Find the mean and standard deviation of the corrected pH measurements.
