4. QUESTION A bakery in Cape Town would like to produce a koeksister that could be marketed to consumers that are health conscious. They experimented with 4 different fats to see which fat was least absorbed by the koeksisters during the deep-frying process. Each fat was used for six batches of one dozen koeksisters each, and the table shows the grams of fat absorbed by each batch of koeksisters g Fat Absorbed in Batch 64 72 68 77 56 95 Fat 1 72 13.34 Fat 2 78 91 97 82 85 77 85 7.77 Fat 3 75 93 78 71 63 76 76 9.88 Fat 4 55 66 49 64 70 68 62 8.22 S df MS F p-value Treatment 1636.5 545.4 5.41 0.0069 Error 2018.0 20 100.9 Total 3654.5 23 4.1 At the 0.05 level of significance, test whether the mean fat absorbed by the four different fats are significantly different.
