Please, determine the appropriate value(s) of -Za, Za, +- Z(a/2) and round to two decimal places as needed. A manufacturer of detergent claims that the contents of boxes sold weigh on average at least 12 ounces. The distribution of weight is known to be normal, with a standard deviation of 0.5 ounces. A random sample of 16 boxes yielded a sample mean weight of 11.23 ounces. Test at the 1% significance level the null hypothesis that the population mean weight...
