Correct answer will be given Brainliest and will i will also follow if the answer is right.
Spams and wrong answer would be reported and maybe the account would be deleted too. So please answer the question only if you know the answer. Thank you!A bank manager is designing a system that is intended to decrease the variance of the time customers wait before their term comes. Under old system, a random sample of 11 customers had a variance of 400. Under the new system, a random sample of 21 customers had a variance of 256. At alpha =0.05 is there enough evidence to convince the manager to switch to the new system? Assume both populations are normally distributed. If V, and V2. be the respective velocities of a planet when it is
nearest and farthest from the sun, then prove that
(1 - e) V = (1+e) V2,
where e is the eccentricity of the planet's orbit. [C. H. 2002; T. H. 2003]
