Consider a chain discount of 20/15/10 instead of the single discount. What would the net price equivalent rate be?

2021-01-07
Let the price be x. The chain the gives:
(1st) 1x-0.2x=0.8x
(2nd) (1-0.15)(1x-0.2x)=0.68x
(3rd) (1-0.1)(0.68x)=0.612x
The net price equivalent rate is 0.612=61.2% of the original price.

The method uses a numerical measure of the distribution of gaps, or the sizes of holes, in the pixel, called lacunarity. Summary statistics for the lacunarity measurements in a sample of 100 grassland pixels are x¯=225 and s=20s=20. It is known that the mean lacunarity measurement for all grassland pixels is 220. The method will be effective in identifying land cover if the standard deviation of the measurements is 10% (or less) of the true mean (i.e., if the standard deviation is less than 22). a. Give the null and alternative hypotheses for a test to determine whether, in fact, the standard deviation of all grassland pixels is less than 22. b. A MINITAB analysis of the data is provided below.
