Q1) Researcher forecasts that listening to music while solving math problems will make particular brain area more active. To test this, research participant has her brain scanned during listening to music and solving math problems and brain area of interest has percent signal change of 58. From many earlier studies with this same math-problems procedure (but not listening to music), it is known that signal change in this brain area is normally distributed with mean of 35 and standard deviation of 10. By using .01 level, what must researcher conclude? Solve this problem explicitly by using all five steps of hypothesis testing and demonstrate your answer with sketch showing comparison distribution. Then describe your answer to someone who has never taken a statistic course (but who is familiar with mean, standard of deviation and Z scores).
