Hello, may you please help me to answer these questions? There are two questions here, and what I want to see per questions are (A) how you compute it manually, preferably handwritten, I understand it that way. (B) how you verify your answer in SPSS, including the table and how you obtain that. Thank you so much, I hope that you will help me.

ANOVA An ecological study was conducted to compare the rates of growth of vegetation at four swampy undeveloped sites and to determine the cause of any differences that might be observed. Part of the study involved measuring the leaf lengths of a particular plant species on a preselected date in May. Six plants were randomly selected at each of the four sites to be used in the comparison. The data in the table are the leaf length per plant (in centimeters). Do the data provide a sufficient evidence to indicate a difference in mean leaf length among the four locations? Use 0.05 level of signicance. Location 3 Location 4 5.7 6.2 5.4 3.7 5.0 3.2 6.0 3.9 5.6 4.0 4.9 3.5 5.2 3.6 PAIRED SAMPLE T-TEST In a study conducted by the department of Nutrition the following data on the comparison of sorbic acid residuals in parts per million in hotdogs immediately after dipping in a sorbate solution and after 60 days storage were recorded. Sorbic Acid Residuals in Hotdogs Slice Before Storage After Storage 1 224 116 2 270 96 400 239 444 329 590 437 NOVA 660 597 1400 686 8 680 576 Assuming the two are normally distributed. Is there a sufficient evidence, at the 0.05 level of significance, to say that the length of storage influence sorbic acid residual concentrations
