Q5. An experiment was carried out to study the effect of supplementation of nutrient on the body weight of Tilapia fish species grown in the pond on basis of 3-months between supplement and non-supplement groups. Thus, following data are on the weight (in 10grams) of fishes after 3-months in the supplemented group measured for a random sample of 20: 30, 25, 23, 41, 39, 27, 41, 24, 32, 29, 35, 31, 36, 33, 36, 42, 35, 37, 41, and 29 Then, compute mean, median and modal body weight of Tilapia fish. Q6. Consider the following data on the monthly consumption expenditure (in Birr) on staple food crops at Sawula town for a random sample of 85 households Monthly consumption 300-450 450-600 600-750 750-900 900-1050 expenditure (in Birr) Number of households 12 15 30 18 10 Then, compute a. The average the monthly consumption expenditure (in Birr) on staple food crops at Sawula town b. The median value of the monthly consumption expenditure (in Birr) on staple food crops at Sawula town c. The modal value of the monthly consumption expenditure (in Birr) on staple food crops at Sawula town d. A value for which 25% of the monthly consumption expenditure (in Birr) on staple food crops at Sawula town lies above it e. A value for which 75% of the monthly consumption expenditure (in Birr) on staple food crops at Sawula town lies above it f. Check that a value of second quartile, 5 deciles, 50 percentile and median value of the monthly consumption expenditure (in Birr) on staple food crops at Sawula town are equal Page 2 of 4
