I probably shouldn't be asking this question as I'm relatively scientifically challenged. But I have read numerous facts that scientists can take the preserved DNA of a dinosaur and re-create. Why has this not happened? Was I misled and it's not possible afterall? Please, feel free to fill me in on the currencies of this matter. Having a life-long fascination with dinosaurs, this is something I've always wondered about. Thanks in advance.

3) An automobile mileage study tested the following hypothesis.

H0: μ > 25mpgManufacturer’s claim supported
Ha: μ < 25mpgManufacturer’s claim rejected; average mileage per gallon less than stated

For sigma = 3 and an alpha .02 level of significance, what sample size would be recommended if the researcher wants an 80% chance of that μ is less than 25 miles per gallon when it is actually 24?

Thanks in advance for your help.
