The zoologist uses the same model to study populations for animals other than birds. The zoologist consults with
park planners that want to introduce a species of rabbit
whose population will grow at a rate of 80 rabbits per
year. If the initial population of these rabbits is 5,000,
what should the critical point for these rabbits be to
achieve the desired population growth? (Round your
answer to the nearest whole number.)

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
