Solve and show your solution 2. Set M is a normally distributed set of scores with =17.4 and = 2.5. What is the area of the region between the scores 19.9 and 22.4? 3. A research student is testing the growth of aloe vera in hydroponics gardening. The average height of the aloe vera is 10.6 cm with standard deviation of 1.3 cm. What is the percentage of aloe vera whose height is between 8.0 cm and 13.2 cm? Check Your Understanding 2 4. Scores on a Literature test have an average of 80 with a standard deviation of 6. What is the Z-score of a student who earned a 74 on the test? 5. Ninety-five percent of the height of Grade 11 students are between 1.42 meters and 1.83 meters. Assuming this data is normally distributed, what are the mean height and standard deviation? Solve and show your solution 2. Set M is a normally distributed set of scores with =17.4 and = 2.5.
