can someone show me how to solve this step by step

Chapter Exercise 9-80 At Ajax Spring Water, a half-liter bottle of soft drink is supposed to contain a mean of 513 ml. The lling process follows a normal distribution with a known process standard deviation of 9 ml. (3) The normal distribution should be used for the sample mean because (You may select more than one answer. Click the box with a check mark for the correct answer and click to empty the box for the wrong answer.) the sample population has a large mean. the population distribution is known to be normal. the population standard deviation is known. the standard deviation is very small. (b) Set up hypotheses and a two-tailed decision rule for the correct mean using the 5 percent level of signicance. The hypothesis for a two-tailed decision is a. Hg: u513, H1:,u = 513, reject ifz 1.96 b. H0: ,u513, H1: ,u = 513. reject ifz > 1.96 orz 1.96 orz -1.96 orz
