The data on Sheet1 shows strength data for 50 samples from each of five suppliers. Do all suppliers provide the same strength of product? Run an ANOVA on the data. Provide a plot of results (e.g. Tukey HSD plot).If any supplier is different than the rest, which supplier(s) is it? Supplier E is supposed to have a superior product. Does the tear strength of this supplier beat the strengths reported by other suppliers? Assuming equal variances, what is the value of the test statistic? Provide a plot that shows the results of your t test.
