You have just conducted an analysis of variance on three groups, which has led you to reject the null hypothesis. now you want to know which of the groups are different from each other, so you decide to conduct three t tests, each at the .05 level of significance. what are the approximate chances that at least one of those t tests will produce a significant result, even if the groups being compared really do come from populations with the same mean?

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
