Question 2.6 Run the same analyses on the small and large samples that you previously ran on the full dataset and on the convenience sample. Compare the accuracy of the estimates of the population statistics that we get from the convenience sample, the small simple random sample, and the large simple random sample. (Just notice this for yourself -- the autograder will check your sample statistics but will not validate whatever you do to compare.)

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
