A standardized exam's scores are normally distributed. In a recent year, the mean test score was 21.4 and the standard deviation was 5.3. The lest scores of four students selected at random are 15, 24, 8, and 36. Find the z-scores that correspond to each value and determine whether any of the values are unusual The 2-score for 15 is (Round to two decimal places as needed) The 2-score for 24 is (Round to two decimal places as needed.) The z-score for 8 is (Round to two decimal places as needed) The 2-score for 36 is (Round to two decimal places as needed) Which values, if any, are unusual? Select the correct choice below and, if necessary, fill in the answer box within your choice. OA. The unusual value(s) is/are (Use a comma to separate answers as needed.) OB. None of the values are unusual
Systolic blood pressure readings are normally distributed with a mean of 121 and standard deviation of 15. If a person from the population was selected at random, find the probability that their blood pressure is in the acceptable range (between 114 and 140) for an athletic activity. A. Label and shade the normal distribution curve to model this problem.
