Question 1
For the dataset: 20, 20, 10, 10, 40, 50, 20, 30, 10, 20, 50, 60, 20, 30, 50, 20, 30, 40, 30, 30, 30, 50, 40 calculate the max, min, mode, median and mean.(20%)
Draw a boxplot with inner and outer fence
For the data in part (i), if the value 60 was replaced by 2000, what would you call this value in the dataset? What could be the explanation for such a value? How can you through the boxplot decide if this value should be excluded from your analysis
Draw a histogram of the data with four equal sized classes and comment how close to a normal distribution the data look like being
What would be the new values for the three measures of central location with the value of 2000 instead of 60. Comment on the differences
Calculate the coefficient of variation for the population from which the data are drawn.

Draw the supply curve and demand curve independently in a
separate graph.
Write the demand equation and the supply equation.
Combine both curves in one graph and show the equilibrium price
and quantity.
What is the quantity demanded when the price is $10?
Is there a shortage or surplus when the price equals
$8? What about $4?
