A consumer electronics company is comparing two different types
of batteries for
use in its RC toy cars. Battery X has mean battery life of μ1,
while Battery Y
has mean battery life of μ2 hours. The standard deviation is
assumed to be 0.5 for
both batteries. A random sample of n = 20 batteries of each type is
selected with
̄x − ̄y = 0.01. Please construct a a CI with 95% confidence for μ1
−μ2.
