(a)
To explain: The provided pair of variables as response, explanatory or neither.
To explain: The provided pair of variables is neither response nor explanatory.
(b)
To explain: The given pair of variables as response, explanatory or neither.
To explain: The variable “the number of pages in the textbook” is explanatory and the variable “the cost of new copy of the textbook” is a response variable.
(c)
To explain: The given pair of variables as response, explanatory or neither.
To explain: The variable “the number of alcoholic drinks consumed” is explanatory and the variable “the blood alcohol content” is a response variable.
(d)
To explain: The given pair of variables as response, explanatory or neither.
To explain: The variable “the dose of vitamin D given each day a year” is explanatory and the variable “the change in total bone mineral content since the beginning of the study” is a response variable.

- 9. The concentration function of a random variable X is defined as Qx(h) = sup P(x ≤ X ≤x+h), h>0. Show that, if X and Y are independent random variables, then Qx+y (h) min{Qx(h). Qr (h)).arrow_forward10. Prove that, if (t)=1+0(12) as asf->> O is a characteristic function, then p = 1.arrow_forward9. The concentration function of a random variable X is defined as Qx(h) sup P(x ≤x≤x+h), h>0. (b) Is it true that Qx(ah) =aQx (h)?arrow_forward

(a) Prove that is a characteristic function. (b) Prove that the corresponding distribution is absolutely continuous. (c) Prove, departing from itself, that the distribution has finite mean and variance. (d) Prove, without computation, that the mean equals 0. (e) Compute the density.arrow_forward1.
