If correct i will give brainliest and 5 stars! a leading marketing research firm conducted a telephone survey of 325 young adults, 21 years of age, to estimate the average amount of money they intend on spending on political contributions during their first federal election cycle. the data are distributed normally, with the highest amount being $975.00 and the lowest amount being $20.00. the sample mean is $75.00. what is the margin of error (me), rounded to the nearest hundredth, for these first-time voters?

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?
