Bob boards a ferris wheel that spins in the counterclockwise direction. The wheel has a radius of 100 ft. The ride lasts 12 minutes and consistes of 3 complete revolutions. Bob reaches the top for the first time 100 seconds after boarding the wheel. Required:
a. Impose a coordinate system with the origin at the center of the wheel and the top point on the positive y-axis. What are Bob's coordinates at any time t?
b. What are Bob's coordinates after 1 minute?

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
