To estimate the mean score $\mu$ of those who took the Medical College Admission Test on your campus, you will obtain the scores of an SRS of students. From published information you know that the scores are approximately Normal with standard deviation about 6.3. You want your sample mean $\bar{x}$ to estimate $\mu$ with an error of no more than 1 point in either direction. How large an SRS do you need in order to reduce the standard deviation of $\bar{x}$ to the value you found? Give your answer rounded up to the nearest whole number. SRS size:
The Concorde was a supersonic aircraft used for trans-Atlantic travel in the 1980s and 1990s, having a length of 61.0 m when sitting on the ground on a typical day when the temperature is 14.0 ∘C . The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 30.0 cm . (The passenger cabin is on rollers, so the airplane expands around the passenger cabin.) Take the coefficient of linear expansion for aluminum to be α = 2.40×10−5 /∘C . Part A What is the temperature T of the Concorde's skin in flight? View Available Hint(s)
