Compute the mean and standard deviation of the following collected data scores: 10, 7, 9, 5, 12, 9, 6, 8, 5, 8, 6, 9, 5, 8, 10, 8, 12, 9, 5, 7

1. Use the empirical rule, to answer the following questions

a. What is the interval or range of scores falls within 68%?

b. What is the interval or range of scores falls within 95%?

c. What is the interval or range of scores falls within 99.7%?

d. What is the interval or range of scores falls within 81.5%? e. In which interval away from the mean does your score belong?

2. Illustrate the distribution of the data you obtained from this survey through a

diagram and put a mark on the interval where your score located.

For instance, one of your friends from another school asks your help about his problem in Statistics and Probability. He needs to answer his assignment but unfortunately, he left his module in the school. He wants to know how to identify the regions under the normal curve corresponding to different standard norma values. Your friend will send a picture of a normal curve with the corresponding area, and he asks you favor to explain each picture on how to obtain the value of the shaded part of the normal curves. Here is the screenshot of the pictures: Elson 0117 0.9698 196 Make your messagemunicipality. He was already submitted the different requirements like ITR of his parents and G10 Report Card.
