• What is the difference between a discrete uniform distribution and a continuous uniform distribution?
• A discrete uniform distribution results from recording the final digit of the cell phone number for 3,000 students. In order to be a density curve, what would be the height (or probability) for each of the bars corresponding to the 10 possible outcomes of 0 to 9, inclusive?
• A discrete uniform distribution results from recording the final digit of the cell phone number for 3,000 students. What is the mean of this distribution?
• Assume that a gallon of milk bought at the store goes bad some time in the interval from 5 days to 10 days after purchase. What is the probability that a randomly chosen gallon of milk goes bad between 6 and 8 days after purchase?
• Assume that a gallon of milk bought at the store goes bad some time in the interval from 5 days to 10 days after purchase. What is the probability that it goes bad less than 4.5 days after purchase?
• Assume that a gallon of milk bought at the store goes bad some time in the interval from 5 days to 10 days after purchase. What is the standard deviation of this distribution?
• What are the properties of a density curve in statistics?
• How do you find probabiities using a density curve?
• a) How to plot the demand and supply curves on a two-dimensional diagram ? b) What is the equilibrium price and equilibrium quantity traded ? c) What is the value of excess demand or supply when price is (i) $8, (ii) $13 ?
• Positive integers from 1 to 45, inclusive are placed in 5 groups of 9 each. What is the highest possible average of the medians of these 5 groups?
