Kepler's Third Law of Orbital Motion shows how you can approximate the period P (in Earth years) it takes a planet to complete one orbit of the sun. Use the function P = dt, where d is the
distance from the planet to the sun in astronomical units (AU-about 930,000,000 miles or the
distance from Earth to the sun). Find the approximate length (in Earth years) of a Venusian
year if Venus is 0.72 AU from the sun.

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
