Suppose that you have purchased a filling machine for candy bags that is supposed to fill each bag with 1414 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 9 bags yields the following data (in oz):

1 point) Suppose that you have purchased a filling machine for candy bags that is supposed to fill each bag with 14 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 9 bags yields the following data (in oz): 13.66 14.73 13.63 14.71 13.09 13.57 13.61 13.72 13.4 Using -0.05, can you conclude that the mean fill weight is actually less than 14 by computing the following (a) the degree of freedom (b) the critical t value (c) the test statistics 0.16757 The final conclusion i:s A. There is not sufficient evidence to reject the null hypothesis that -14. Our results do not provide enough evidence that mean weight is less 14 B. We can reject the null hypothesis that = 14

Explanation / Answer

13.66 14.73 13.63 14.71 13.09 13.57 13.61 13.72 13.4 n 9.00 mean 13.7911111 SD 0.55904929 df 8 t = 13.79 - 14 / ( 0.559 / srqt 9 ) t= -1.127 critical value for alpha = 0.05 df=8 is 2.306 since t > critical value we fail to rejct Ho
