Scores on a quiz are normally distributed with a mean of 9.6 and a standard deviation of 3. Compute the z score for a quiz score of 10. Round your final answer to three decimal places.
If the mean exam score of a class was 75%, with a standard deviation of 15%, what percent of students would be expected score at or higher than 92%? Assume that the distribution of the scores is normal and the variable is random.
A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1479 and the standard deviation was 316. The test scores of four students selected at random are 1880, 1220, 2180, and 1380. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 1880 is Round to two decimal places as needed.) The z-score for 1220 is (Round to two decimal places as needed) The...
