1 (50 pts). A cоmpаny mаnufаctures chоcоlate bars. The expected mean weight is 8.0 ounces. A worker wants to know whether the products under his supervision satisfy the requirement. A sample of 25 chocolate bars is selected. The sample mean weight x-- =7.92 and the sample standard deviation s = 0.11. (a) What is the population? What is the sample? (b) At α = 0.01 level of significance, determine whether there is evidence that the population mean weight of the chocolate bars is different from 8.0 ounces. (c) Identify the type of error for your conclusion. Find the probability of error and probability of confidence if it is type I error.
