3. A performance evaluation for AUS Enterprise was administered to several departments, with mean and sample sizes as follows. Calculate a combined mean for all departments. Human Resource Operations * 91 N2 = 30 Security = 86 Ny = 10 Accounting X.= 84 X= 80 N =6 Na = 8 4. The cost of 12 models of mobile phones at a cellular specialty store during 2009 was as follows: P5 500, P10 200, P9 750, PG 800, P14 000, P12 000, P13 000, P23 000, P 12 900, P10 000, P11 000, P13 000. 5. A manufacturer of rechargeable batteries took a sample of 15 batteries from a day's production and used them continuously until they were worn out. The number of recharged until failure were; 20, 45, 23, 21, 23 ,32 „34, 23, 23, 21, 21, 21, 22, 32, 32. Find the median. 6. Consider the sample 30, 46, 50, 44, 52, 53, 61, 48, 35, and 51. Find the midrange. 7. Consider the sample 87, 84, 76, 70, 76, 80, 63, 76, 39, 90, 76,77, and 80. Find the mode
