In studying animal populations we often employ "capturing, marking, releasing, recapturing", using the equation N/M=n/R, where N= total population; M=# of individuals marked; n=# of individuals re-captured without mark; R=# of individuals re-captured with mark. here we are studying a population of rabbits species on an island. First, estimate the total population of the rabbit species with M=100, n=95, & R=5. Second, after one year estimate the total population again of the rabbit species with M=200, n=190, & R=10. Please...
*related to R programming* Using simulation, estimate the coverage for the t-based interval ☺ ta/2,n-1.sx/vn for a population mean y using a confidence level of c = 0.9 with: a. a random sample of size 10 from a standard Gaussian population b. a random sample of size 10 from a standard Exponential population Use prop.test() to determine a confidence interval for the true coverage in both cases. Does the t-based interval attain the desired coverage in the Gaussian case? In...
