The average daily high temperature in June in LA is 77◦F with a standard deviation of 5◦F. Suppose that the temperatures in June closely follow a normal distribution.
(a) Write the probability model for the distribution of temperature in ◦C in June in LA.
(b) What is the probability of observing a 28◦C (which roughly corresponds to 83◦F) temperature
or higher in June in LA? Calculate using the ◦C model from part (a).
(c) Did you get the same answer or different answers in part (b) of this question and part (a) of
Exercise 3.7? Are you surprised? Explain.
(d) Estimate the IQR of the temperatures (in ◦C) in June in LA.
