-1 are i Noah and Lin are each trying to solve the equation z? - 6x + 10 = 0. They know that the solutions to zº = -
and -i, but they are not sure how to use this information to solve for x in their equation.
Here is Noah's work:
x2 - 6x + 10 = 0
x2 - 6x = -10
x2 - 6x + 9 = -10 + 9
(x-3) = -1
Show how Noah can finish his work using complex numbers.

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
