- FIVE. Which of the following is true about standard deviation? The first step in calculating the standard deviation is calculating the square root. The second step in calculating the standard deviation is to subtract each measurement from the intermediate value and then square that difference. The last step in calculating the standard deviation is to sum the squared values and divide by the number of values minus one. Standard deviation is a type of average where the positive and negative numbers sum to zero. The amount of difference of the measurements from the central value is called the sample standard deviation.arrow_forwardDefine reciprocity.arrow_forwardA class uses weighted averages to calculate your course grade.

- R(p) = pN(p).| Bob is currently selling tires for 60 dollars each. His weekly sales are running at 130 tires per week, so N(60) = 130. His marketing department estimates that he will lose 2 sales per week for each 10 dollar increase in unit price, so N'(60) = -0.2. Estimate Bob's increase in weekly revenue for each one dollar increase in tire price.

By 1992, self-service outlets sold nearly 80% of all US gas, and only New Jersey and Oregon continued to ban self- service sales. Using predictive value for self-service sales for New Jersey and Oregon Johnson and Romeo (2000) estimate that the ban in those two states raised the price by approximately $.03-$.05 per gallon. Why did the ban effect the price? Illustrate using a figure and explain. Show the welfare effects in your figure.
