Suppose that the class average for PSYC292 at the end of the course was 58% with a standard deviation of 19%. The instructor decides to rescale the scores to have a new mean of 72%.
a. If the instructor wants 10% of the class to earn a grade of 88% or greater, what should they set the standard deviation to?
b. If the original grade was 75%, what will the rescaled grade be? If the rescaled grade is 75%, what was the original grade? Round your answers to the nearest whole percentage. Note: If you were unable to compute a standard deviation in part (a), use a SD of 10 for the rescaled scores.

An automated water dispenser fills packets with one liter of water on average, with a standard deviation of 5 milliliter. the manual says that after a year of operation the dispenser should be tested to see if it needs recalibration. a year later a number of filled packets are set aside and measured separately. it is found that the average packet now contains about 0.995 liters. does the dispenser need calibration? explain your answer.
