You have conducted an experiment to measure two values x and y, and have obtained the following data. x values: mean=4.8, SD=0.36, number of data points: 36 y values: mean=6.6, SD=0.28, number of data points: 49 (a) Calculate the extremities of the error bars in x and y. (b) Calculate the estimated values of the quantities x+y, xy, and ln(x), including the error bars. (c) Define a range of x in which the true value of x must lie with 99% probability. (Round all answer upto 2 decimal places) x+y : __a__ __b__.
