'The distribution Of raw scores on a particular achievement test has a mean of 500 and a standard deviation of 80. If each score is increased by 25, what will be the mean and standard deviation of the distribution of new scores? Choose 1 answer: Mean: 525 Standard deviation: 105 Mean: 525 Standard deviation: 80 Mean: 500 Standard deviation: 105 Mean: 500 Standard deviation: 80'
