Temperature in LA
The
average daily high temperature in June in LA is 79°F with a standard deviation of 6°F. Suppose that the
temperatures in June closely follow a normal distribution.
(a) What is the probability of observing a 89°F temperature or higher in LA during a randomly chosen day in June?
(b) What is the probability of observing a 84°F temperature or lower in LA during a randomly chosen day in June?
(c) What is the probability of observing a temperature between 75°F and 89°F in LA during a randomly chosen day in
June?
(d) Find a temperature so that 60% of days will be warmer during June in LA.
