The table shows the test scores of students who studied for a test as a group (Group A) and students who studied individually (Group B). Which would be the best measures of center and variation to use to compare the data? The scores of Group B are skewed right, so the mean and range are the best measures for comparison. Both distributions are nearly symmetric, so the mean and the standard deviation are the best measures for comparison. Both distributions are nearly symmetric, so the median and the interquartile range are the best measures for comparison. The scores of both groups are skewed, so the median and standard deviation are the best measures for comparison.

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?
