Question

A company makes car batteries and claims 80% of its ABC batteries are good for 70 months or longer. Assume that this claim is true. Let p
ˆ
be the proportion in a sample of 100 such ABC
batteries. What is the probability that this sample proportion is within 0.05 of the population proportion.

Answer 1

initial velocity =u=0

velocity =distance /time

=(5.96+0.08n)/9=v

v=u+at

a=(v-u) /t

a=(5.96+0.08n)*9/9

a=5.96+0.08n
