Although the packages are labeled as 8 ounces, the company wants the packages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically, and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in a particular sample of 50 packages, the mean amount dispensed is 8.167 ounces, with a sample standard deviation of 0.055 ounce. Complete parts (a) and (b) a. Is there evidence that the population mean amount is different from 8.17 ounces? (Use a 0.01 level of significance.) State the null and altenative hypotheses H0: = 8.17 H1: 8.17 Type integers or decimals.) Identify the critical value(s) The critical value(s) is(are) Round to four decimal places as needed. Use a comma to separate answers as needed.) Enter your answer in the answer box and then click Check Answer parts Clear All Check Answe

Explanation / Answer

here for (50-1=49) degree of freedom and 0.01 level critical vlaues are -2.6800 ; 2.6800

std error =std deviation/(n)1/2 =0.0078

test statistic t=(X-mean)/std error =(8.167-8.17)/0.0078=-0.3857

as test statistic is not in critical region we can njot reejct null hypothesis

( please revert if any other sub part is there
