Suppose that a random sample or size n = 5 was selected from the vineyard properties for sale in Sonoma County, California, in each of 3 years. The following data are consistent with summary information on price per acre (in dollars, rounded to the nearest thousand) for disease resistant grape vineyards in Sonoma County ( Wines and Vines, November 1999). l 996 30,000 34,000 36,000 38,000 40,000 1997 30,000 35,000 37,000 38,000 40,000 1998 40,000 41,000 43,000 44,000 50,000 a. Construct boxplots for each of the 3years on a common axis, and label each by year. Comment on the similarities and b. Carry out an ANOVA to determine whether there is evidence to support the claim that the mean price per acre for vineyard land in Sonoma County was not the same for the 3years Use a significance level of 0.05 for your test.
