Problem 3 In a study, the calcium content in wheat from a certain area for four different storage times was investigated. The data is shown in the table below. Storage Observations Period Average Std. Dev 0 month 58.75 57.94 58.91 56.85 55.21 57.3 57.49 1.37 1 month 58.87 56.43 56.51 57.67 59.75 58.48 57.95 1.33 2 months 59.13 60.38 58.01 59.95 59.51 60.34 59.55 0.9 4 months 62.32 58.76 60.03 59.36 59.61 61.95 60.34 1.46 Use the data above to answer the following questions: a) Is there sufficient evidence to conclude that the mean calcium content is not the same for the different storage times? Test at a significance level of $\alpha$ = 0.05 b) Use a 95% confidence interval to compare the mean calcium content in wheat stored for 0 month with the mean calcium content in wheat stored for 4 month. Comment on your results. What assumption(s) did you make?
