s project will examine various concepts in inferential statistics. You will view lecture videos and respond to the questions that follow. There are four questions worth 25 points each. Show all work, where appropriate, to receive full credit. A goodness-of-fit test, covered in Section 12.1 of the textbook, is defined by Sullivan as, "...an inferential procedure us to determine whether a frequency distribution follows a specific distribution." View this video and use the same procedure to solve the following two problems: https://youtu.be/2QeDRsxSF9M Please note that the table referenced in the video can be found at the bottom of this webpage: https://en.wikipedia.org/wiki/Chi-squared_distribution Clearly state your hypotheses, test statistic, and conclusion. 1) A teacher figures that final grades in the chemistry department are distributed as: A, 25%; B, 25%; C, 40%; D, 5%; F, 5%. At the end of a randomly selected semester, the following number of grades were recorded. Determine if the grade distribution for the department is different than expected. Use a = 0.01. Grade A B C D F Expected % 25 25 40 5 5 Observed 36 42 60 8 14
