For this assignment I just need you to follow the paper uploaded and submit accordingly. Please pay attention to the details and make sure it is on point. This assignment is worth 50 points. It is due 11/12 by 9pm EST. Here is message from teacher: Dear class, Hope the message finds you all well and healthy. Because many of you asked questions regarding Question 2 (items 1-4). Below are some hints for you to consider. ================================================================ What you need to know is the proportions under the curse based on the standard normal distribution curve. For instance, the mean would be located in the middle. So you have to add the proportions under the curve from the very left side to the middle. It would be 50%. Assume that the population (400,000 students) is 100%. How many students for 50% of the population? Below are some concepts regarding the percentile, z score, and normal distribution curve. (1) The high percentile represents high-performance compared to others; (2-1) The z score includes positive and negative scores. In the normal curve, the negative value will be located on the left side of the curve, indicating low performance and low percentile. (2-2) The z score of 0 will be located in the middle. If you add the proportions under the curve from the very left to the middle, it would be 50%. That is, your score is the mean of the population (i.e., z score of 0), you have a 50th percentile. (2-3) In the normal curve, the positive value will be located on the right side of the curve, indicating high performance and high percentile. ================================================================ Hope the information is helpful for you to answer all items in Question 2.
