Integrate x2 between -1 and 3 between using both the stone throwing approach and the mean value approach. For m=1 & N=1000, what do you observe if you plot N vs calculated value of the function for both methods? For N=102, 103,104, 105, 106 and m=16 plot the N vs absolute error for both methods. What relationship fits this distribution of points? Comment on what you observe Now plot N against the Standard Deviation (the Variance) for both methods and comment on what you observe.
For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.
