I am stuck on number three. What do I insert to N, Count, and sample for the theory based inference applet?

Chapter 03.3 Exercise Question 08 In a precourse, anonymous survey of students in her introductory statistics course, one of the authors asked her students how many hours per week they expected to spend studying statistics outside of class. 36 students responded to that question, with an average of 7.96 hours and a SD of 3.68 hours. The data were not strongly skewed. Identify the observational unit for this study. LINK TO TEXT Identify the variable of interest and whether it is categorical or quantitative. LINK TO TEXT Use the Theory-Based Inference applet to calculate and report the 95% confidence interval for the parameter of interest. Round answers to 4 decimal places, e.g. 0.7523. The confidence interval is to LINK TO TEXT In the context of this study, was it valid to use the theory-based (t-distribution) approach to find a confidence interval? Explain your reasoning
