Q-1 A laboontory experiment is conducted to measure the viscosity of cestrin oil. A series of tests gives the values as 0.033,0.034,0.044,0.035, 0.032,0.033,0.036,0.034, and 0.032ft/s. Calculate the mean reading, the variance, the Standard deviation, and the unceotainity in the calculated mean value. Estimate any data points are necessary. Q-2 A resiltunce arrangement of 40 B desired. Tau resistances of 80.00.1 and two resittuces of 20.00.02 are available. Which should be used, a series arrangement with the 20. resibtors or a Barrulal crrangement with the 80 resittrs? Calculate the uncestuinity and Iustify your selection
