An instructor in a college class recently gave an exam that was worth a total of 100 points. The instructor inadvertently made the exam harder than he had intended. The scores were very symmetric, but the average score for his students was 43 and the standard deviation of the scores was 5 points. The instructor is considering 2 different strategies for rescaling the exam results: Method 1:Add 17 points to everyone's score. Method 2:Multiply everyone's score by 1.7. Which of the following are true? A) Method 1 will increase the standard deviation of the students' scoresB) Method 2 will increase the standard deviation of the students' scores.C) Method 1 will decrease the standard deviation of the students' scores.D) Method 2 will decrease the standard deviation of the students' scores.

Very confused please help. In problem #s 1 and 2, use the following information.The indicated airspeed S (in knots) of an airplane is given by an airspeed indicator that measures the difference p (in inches of mercury) between the static and dynamic pressures. The relationship between S and p can be modeled by S=136.4p+4.5.1. Find the differential pressure when the indicated airspeed is 157 knots.2. Find the change in the differential pressure of an airplane that was traveling at 218 knots and slowed down to 195 knots.In problem #s 3 and 4, use the following information.The true airspeed T (in knots) of an airplane can be modeled by T=(1+A50,000) S, where A is the altitude (in feet) and S is the indicated airspeed (in knots).3. Write the equation for true airspeed T in terms of altitude and differential pressure p.4. A plane is flying with a true airspeed of 280 knots at an altitude of 20,000 feet. Estimate the differential pressure. Explain why you think your estimate is correct.
