History and Development of Statistics Simple forms of statistics have been used since the beginning of civilization‚ when pictorial representations or other symbols were used to record numbers of people‚ animals‚ and inanimate objects on skins‚ slabs‚ or sticks of wood and the walls of caves. Before 3000 BC theBabylonians used small clay tablets to record tabulations of agricultural yields and of commodities bartered or sold. The Egyptians analyzed the population and material wealth of their country

Tab 1----All graphs‚ including the histogram should have an appropriate title and the x and y axis should be labeled. Bin and frequency does not give any information as to what is being represented by the numerical data in the histogram (hint: Electricity cost (in $) and one-bedroom apartments). As Professor Ellis stated in the lectures‚ graphs should be able to stand alone. “A Graph should sing its song!” Bin ranges are correct. However‚ the largest percentage does not lie between 139‚ 179.

FREQUENCY DISTRIBUTION WHAT IT IS Frequency distributions summarize and compress data by grouping it into classes and recording how many data points fall into each class. That is‚ they show how many observations on a given variable have a particular attribute. For example‚ a survey is taken of 50 people’s favorite color. The frequency distribution might indicate 15 people selected green‚ 12 blue‚ 6 red‚ 7 yellow‚ and 10 purple. Converting these raw numbers into percentages would then provide an

Each loan has a 5% probability of default‚ in which case the bank is not repaid anything. The chance of default is independent across all the loans. Bank B has only one loan of $100 million outstanding‚ which it also expects will be repaid today. It also has a 5% probability of not being repaid. Explain the difference between the type of risk each bank faces. Which bank faces less risk? Why? The expected payoffs are the same‚ but bank A is less risky.
