2. Random samples of students from three different clusters of Open University Malaysia were asked how much time they spend per week studying. The results (in minutes) for the three clusters are collected from sample of n,=5, n2=4 and n3=3. A partially completed Analysis of Variance table is shown in Table 1. Table 1 Source Sum of Degrees of Squares Freedom Mean Square F Treatments 9517.3 (ii) (v) (vii) Error 6310.7 iii) (vi) Total (i) (iv) (a) Calculate the value for (i)-(vii) from the table. ( 14) (b) Conduct an appropriate hypothesis test to test whether all cluster means are equal using a = 0.05
