The battery life of a fully charge iPhone 13 Pro on a standby
follows a normally distributed with mean
μ = 7 hour and variance σ2= 1 hours.
(a) Write out the integral form of the probability that a
fully-charged iPhone 13 Pro last between 7
and 9 hours on standby. then use the pnorm function in R to find
this probability.
(b) What is the probability that a fully-charged iPhone 13 Pro last
less than 5 hours?
(c) What is the probability that a fully-charged iPhone 13 Pro last
more than 9 hours?
(d) What is the minimum time a fully-charged iPhone 13 Pro need to
last in order to be in the top
10% best quality?
