Aline in the xy-plane that passes through the coordinate points (3, -6) and (–7, –4) will never intersecta line that is represented by which of the following equations?
a, x+5y=6
b, x+(y/2)=7
c, y-2x=-9
d, 2y-x=-8

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
