Development of Efficient Market Hypothesis The development of the efficient market hypothesis has implications for the development of accounting theory and practice. It is important for accountants to realize that there are many intelligent analysts interpreting the data and‚ as long as sufficiently accurate information is presented‚ the analyst is likely to work around differences in the exact form of a balance sheet or income statement.

heavier then it adds mass and will slow down so the force hitting the second car won’t be as strong so the acceleration will be slower. So if the first car’s mass is lighter than the second car will accelerate faster. Analyze Results: I reject my hypothesis that if the first car has less mass then the second car will have a greater acceleration. My data shows that as the first car gains mass the second car will accelerate more‚ for example: when the mass of the first car is at 0 grams it accelerates
