Satu sampel rawak yang terdiri daripada 24 ekor ayam telah diperoleh dan sejenis makanan diberikan kepada setiap 6 ekor ayam (dalam auns) seperti ditunjukkandi bawah. Gunakan a = 0.05 untuk menguji hipotesis nol bahawa purata berat badan ayam semuanya sama. (Petunjuk: Gunakan ujian Kruskal Wallis): In a local farm, chicken was fed four different types of feed to observe the effects of the food on weight gain. A random sample of 24 chickens was obtained ad each type of feed was given to 6 chickens (in ounces) are tabulated below. Use a = 0.05 to test the null hypothesis that the mean weight gain of the chickens are all equal. (Hint: Use Kruskal Wallis test): Feed P Feed Q Feed R Feed S 12.0 11.2 18.3 19.2 16.1 13.1 16.4 15.1 17.2 17.0 22.2 18.8 17.3 10.8 21.3 16.3 13.7 9.9 19.2 17.4 19.1 16.2 14.8 23.2 (4 markah/marks) b.
