## Answer:

No answer provided yet.It appears that the score on this test was simply the number of questions correct. So a mean score of 195 indicates 195/300 questions correct. Approximately 68% of the values should fall within one standard deviation of the mean. One standard deviation is 30. So 1 standard deviation above and below the mean (195+30 & 195-30) puts scores of 165 through 225 within one standard deviation of the mean.
