ounces of coffee per cup In a test of the machine the discharge amounts in 16 randomly chosen cups of coffee from the machine were recorded The sample mean and sample standard deviation were 5 92 fluid ounces and 0 13 fluid ounces respectively If we assume that the discharge amounts are approximately normally distributed is there enough evidence to conclude that the population mean discharge differs from 6 fluid ounces Use the 0 10 level of significance Perform a two tailed test Then complete the parts below Carry your intermediate computations to three or more decimal places If necessary consult a list of formulas a State the null hypothesis Ho and the alternative hypothesis H HO H 0 b Determine the type of test statistic to use Choose one c Find the value of the test statistic Round to three or more decimal places d Find the two critical values Round to three or more decimal places and e Can we conclude that the mean discharge differs from 6 fluid ounces OYes O No X 5 0 0 X O S OSO 0 0 P P S 00 020 O
