Which of the following correctly uses absolute value to show the distance between -70 and 13? |-70 - 13| = |-83| = -83 units |-70 - 13| = |-83| = 83 units |-70 + 13| = |-57| = 57 units |-70 + 13| = |-57| = -57 units'

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
