Question
(b) Bayu Hijau is a famous company providing several types of food seasonings. In one of their mixing operation, starch and dried, powdered vegetables will be mixed in a batch mixer with the initial proportions of dried vegetable to starch were 40:60. The variance of the sample compositions measured in terms of fractional compositions of starch was found to be 0.0815 after 300 s of mixing. [Bayu Hijau adalah syarikat terkenal yang menyediakan beberapa jenis perasa makanan. Dalam salah satu operasi pencampuran mereka, pati dan sayur-sayuran kering dan tepung akan dicampurkan dalam kumpulan pengadun dengan perkadaran awal sayur-sayuran kering hingga pati adalah 40:60. Varians komposisi sampel yang diukur dari segi komposisi pecahan pati didapati 0.0815 setelah 300 s pencampuran.] i. Assume that the starch and the vegetable particles are of approximately the same physical size and that a sample contains 24 particles. Calculate the duration of the mixing to continue to reach the specified maximum sample composition variance of 0.02.
