suppose the profit a Honda dealership makes on the next 5 Accords it sells are:575, 1,004, 924, 1,495, 1,384. Calculate the standard deviation of the sample. (please express your answer using 2 decimal places)
Homework Answers
Standard deviation = square root of summation of squared differences of values from their mean divided by number of values less one
Mean = (575 + 1004 + 924 + 1495 + 1384)/5 = 1076.40
S.D = (((575 - 1076.40)^2 + (1004 - 1076.40)^2 + (924 - 1076.40)^2 + (1495 - 1076.40)^2 + (1384 - 1076.40)^2))/4)^0.5
= 370.71
Hence the standard deviation is 370.71.

A) Suppose that, initially, the price of a car is $10,000, the average consumer makes $50,000 per year, and 4,000 of these cars are sold every month. Then suppose that, a month later, the price of the car is $10,000, the average consumer makes $40,000 per year, and 5,000 of these cars are sold every month. Calculate the income elasticity of demand for these cars. Enter your answer as a decimal number rounded to 3 decimal places. B) Suppose that,...
