The student demonstrated consistent and correct use of mathematical notation and symbols throughout the investigation, as indicated by the inclusion of all symbols and notation. However, there was a lack of explanation for key terms and variables, particularly regarding the normal distribution, which should have been addressed in the introduction. Additionally, some components such as graphs and tables were left unlabeled, which detracted from the fulfillment of the criterion. Nevertheless, the student effectively utilized multiple forms of mathematical representation and provided explanations for mathematical calculations and data presentation, showcasing a thorough understanding of the concepts. Although the student appropriately rounded results at the end of calculations, there was a missed opportunity to state the degree of accuracy for rounded values, which should have been addressed in the text or alongside the rounded values.
