Suppose that in a certain chemical process the reaction time y (hr) is related to the temperature (°F) in the chamber in which the reaction takes place according to the simple linear regression model with equation y = 5.00 −.01x and 휎= .075.a. What is the expected change in reaction time for a 1°F increase in temperature? For a 10°F increase in temperature? (2 marks)b. What is the expected reaction time when temperature is 200°F? When temperature is 250°F? (2 marks)c. Suppose five observations are made independently on reaction time, each onefor atemperature of 250°F. What is the probability that all five observationsarebetween 2.4 and 2.6 hr? (6 marks)d. What is the probability that two independently observed reaction times for temperatures1°apart are such that the time at the higher temperature exceeds the time at the lower temperature

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
