Mrs. garcia’s students were asked to find 220% of 75. each of the students had a different method. amy: “i multiplied 2.20 by 75 to find my answer.” braden: “i created a table with columns for 100%, 100%, 20%, and 220%. then i filled in the table and added the values.” colton: “i created a table with columns for 100%, 10%, 10%, and 220%. then i filled in the table and added the values.” danielle: “i divided 75 by 5 to find 20%. then i added 75 twice to what i found to get my final answer.” if all of the students completed their steps accurately, which student got the answer wrong?

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
