(2) Meet the assumptions; Interval/Ratio (3) Single sample against a criterion or population mean (also must have the population standard deviation) (4) Find your Z-score. (5) Create the normal distribution. (6) Locate your Z-score on the distribution. Task 1: The following data are the midterm grades for the Fall 2020 and Fall 2021 Statistics courses. These data will serve as the population. In complete and concise sentences: (1) Discuss the populations or samples. (2) Find and summarize the measures of central tendency for both populations or samples. (3) Find and summarize the measure of variability for both populations or samples. In your summary Interpret the finding's. (4) What are the means () and standard deviations ()7 Explain the process of how you arrived at your answer and Interpret your findings. (5) Explain the comparison of the midterm scores from both populations or samples with the average midterm score of the Fall 2020 Statistics course by using z-scores. (6) Based on last week's learning, present the data in a graph. (7) Create a normal distribution, that Includes the population mean, and locate your z score (In the system, you will be able to make two submissions, you can draw or create this distribution in a software program and upload to blackboard). Discuss the skewness and tell me what it means based on your Interpretation of the shape of the distribution. (8) In complete sentences, determine which class had the best grade at midterm.
