1.7. In a simulation exercise, regression model (1.1) applies with Bo = 100, B, = 20, and o? = 25. An observation on Y' will be made for X = 5. a. Can you state the exact probability that Y will fall between 195 and 205? Explain. b. If the normal error regression model (1.24) is applicable, can you now state the exact prob- ability that Y will fall between 195 and 205? If so, state it
