Suppоse we hаve а multivаriate dataset оn used Hоnda HRVs. Further assume that this data consist of below information on a random sample of 100 Honda HRVs. The quantitative variables of interest are: price: Listed sale price mileage: Mileage of the vehicle. age: Age of the vehicle Let denote the variable measurement for the vehicle. Using notation consistent with this course, what would the dimension of the data matrix be for this situation? That is, how many rows and how many columns would there be? What would the dimensions of the sample mean vector and the sample covariance matrix be for this situation? Would you expect the covariance between and to be zero or not? Explain your answers in the context of this situation. Would you expect the covariance between and to be zero or not? Explain your answers in the context of this situation.
