Suppose that in a certain chemical process the reaction time ? (hr) is related to the temperature (OF) in the chamber in which the reaction takes place according to the simple linear regression model with equation y = 4.40-0.01x and ? 0.075. (a) What is the expected change in reaction time for a 1°F increase in temperature? For an 8°F increase in temperature? 1°F increase 8°F increase 01 hr 08 hr (b) What is the expected reaction time when temperature is 220°F? When temperature is 260 F? 2200F 2.2 260°F 1.8 hr hr c) Suppose five observations are made independently on reaction time, each one for a temperature of 260°F. What s the probability that all five times are between 1.66 and 1.94 hours? (Round your answer to four decimal places.) 0124
