A researcher collected daffodils from four sides of a building and from an open area nearby. She wondered whether the average stem length of a daffodil depends on the side of the building on which it is growing. Summary statistics are given in the following table.7 The ANOVA SS(between) is 871.408 and the SS(within) is 3588.54.

(a) Dotplots of these data follow. Based on the dotplots. does it appear that the null hypothesis is true? Why or why not?
(b) State the null hypothesis in symbols.
(c) Construct the ANOVA table and test the null hypothesis. Let α = 0.10.
