The following data on the calcium content of wheat is consistent with summary quantities that appeared in the article "Mineral Contents of Cereal Grains as Affected by Storage and Insect Infestation" (Journal of Stored Products Research [1992]). Four different storage times were considered. Is there sufficient evidence to conclude that the mean calcium content is not the same for the four different storage times? Test the appropriate hypotheses at0.05 level. *You may want to use statistical software such as R or SAS to conduct an appropriate test, but you need to clearly state 1) null and alternative hypotheses, 2) necessary assumptions, 3) test statistic, p-value, and their interpretation, and 4) your final conclusion to the research question. Please attach your code for this analysis in the end.
