  1. The avg daily temperature in degrees Fahrenheit in a certain town is a
  2. normal random variable T with (mean) μt = 30 and (standard deviation)
  3. σt = 12. The daily heating cost C, in dollars, for a building is
  4. related to T by the formula: C = -100T + 13000. What's the probability
  5. that the daily heating cost for this building on a typical day will
  6. exceed $11,500?
