5. Every morning, the depth of a river is measured. It was found that the average height is at 18.25 meters with a standard deviation of 3.1 meters.Assuming that the measurements are normally distributed, what is the probability that the depth of the river will exceed a critical high level of 23 meters? 0.0627 0.4373 0.5627 0.9373 6. The Standards-Based Assessment Exam (SBAE) is an examination given to randomly selected students around the world that aims to identify the quality of education between schools, localities, and countries. Suppose that the results of the SBAE is normally distributed with a mean score of 110 and a standard deviation of 11.2. Approximately what score should a student get if s/he wishes to have a score higher than 90% of all the examinees? 92 96 124 128Ext Feet Statistics and Probability Knowledge Test (10 questions) 1. Which of the following statements is incorrect? O The median is the most appropriate measure of central tendency for highly skewed data distributions The variance in always greater than the standard deviation A 10% trimmed mean of a given data is solved by removing the largest 10% and smallest 10% of the data, then computing for the mean The confficient of variation is the ratio between the mean and the standard deviation. 2.
