Problem:

Item number 1 is done for you. 1. x = 85; mean = 80; standard deviation = 4 85 - 80 Z=. 4 = 1.25 2. x =90; mean = 85; standard deviation = 3 3. x = 78; mean = 75; standard deviation = 6 4. x = 92; mean = 89; standard deviation = 7 5. x = 88; mean = 10; standard deviation = 5Convert the following scores to standard normal scores. Using the formula of X- HI Z=Solve the problem and show the necessary solutions. The scores of students in the 2nd quarter examination for General Mathematics has a mean {a} of 32 and a stande deviation (o) of 4. H'Jaima and Moira obtained z soores of 1.25 and 1.25 respectively, what was their scores in the examination? Let Us Remember Now. let us gather what we have learned. A. Fill in the blanks to complete the thought in each sentence regarding the lesson that you had just learned. I [1] from the normal distribution can be converted into its corresponding value on a [2] I A [3} indicates the number of standard deviations above the mean, while a [4} indicates the number of standard deviations below the mean. I Any normal distribution can be transformed to standard normal distribution by the formula; [5] I To nd the normal value I. use the formula [5]
