Suppose weights of running shoes are normally distributed and have a known population standard deviation of 1 ounces and an unknown population mean. A random sample of 24 running shoes is taken and gives a sample mean of 13 ounces. Identify the parameters needed to calculate a confidence interval at the 80% confidence level. Then find the confidence interval. z0.10 z0.05 z0.025 z0.01 z0.005
1.282 1.645 1.960 2.326 2.576
You may use a calculator or the common z values above.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)
