A group of randomly selected 85 automobile dealers across the automobile industry was surveyed and information about their advertisement expenditure and the total number of cars they sold in particular year was collected. The estimated OLS regression is: Q=3.4+0.09E, where Qi and E denote the quantity of automobiles sold by the ith dealer and their advertisement expenditure, respectively. Calculations show that the regression R 0.45 and 85 Σ (4-02. =841.23. j-1 Based on the given information, the standard error of regression is (Round your answer to two decimal places.) Which of the following statements hold true about the standard error of regression?

A. The standard error of the regression and the regressor have the same measure of unit.
B. The standard error of the regression and the dependent variable are measured in the same unit.
C. The standard error of the regression is an estimator of the standard error of the dependent variable
D. The standard error of the regression is an estimator of the standard deviation of the regression error.

You are making a blueprint of your bedroom and you plan to use a scale factor of 18 . the actual width of your room is 14 feet and the actual length of your room is 16 feet. determine the width and length of your room on the blueprint. on the blueprint, your room will have a width of feet and a length of feet.

Asphere has a diameter of 10 in. what is the volume of the sphere?

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
