Please provide answers:

Suppose you observe a sample data set consisting of In, : 64 inter-arrival times X1, . . . ,X4 for the subway, measured in . . . "d minutes. As before, we assume the statistical model that X1, . . . , X64 \"L. exp (A) for some unknown parameter A > 0. In . . 1 64 i this data set, you observe that the sample mean Is a i=1 X,- 7.8. Additional Instructions: For best results, please adhere to the following guidelines and reminders: 'I. For the upcoming calculations, please truncate gun at 2 decimal places, instead of a more exact value. For example, if (la/2 : 3.84941, use 3.84 instead of 3.85 or 3.849. 2. Input answers truncated at 4 decimal places. For example, if your calculations yield 11.327458, use 11.3274 instead of 11.3275 or 11.32745. 3. You will be computing Cls at asymptotic level 90%.
