A. Graph of a diagonal line with x-axis and y-axis. A line is passing through co-ordinates (-2,3), (0,0) and (2,-3). B. Graph of a diagonal line with x-axis and y-axis. A line is passing through co-ordinates (3,2), and (0,-2). C. Graph of a diagonal line with x-axis and y-axis. A line is passing through co-ordinates (-4,4), (0,-2) and (2,-5). D. Graph of a diagonal line with x-axis and y-axis. A line is passing through co-ordinates (3,0), (0,-2) and (3,-4).

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
