Exercise 1.3.107: apopulation x of rabbits on an island is modeled by x x- (/1000)x, where the independent variable is time in months. at time t = 0, there are 40 rabbits on the island. a) find the solution to the equation with the initial condition. b) how many rabbits are on the island in 1 month, 5 months, 10 months, 15 months (round to the nearest integer) =

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
