Determine which type of hypothesis test is appropriate (if any) in each situation. Type 1: test a population mean, population standard deviation is known Type 2: test a population mean, population standard deviation is unknown Type 3: test a population proportion Clearly state the null and alternative hypothesis. Then, compute the test statistic, and determine the conclusion of the test. A pretzel company claims that its family-size bags of pretzels weigh an average of 12 ounces, with a standard deviation of 0.6 ounces. A group of customers decides to test this claim.
