A machine that is programmed to package 1.95 pounds of cereal in each cereal box is being tested for its accuracy. In a sample of 26 cereal boxes, the mean and the standard deviation are calculated as 1.99 pounds and 0.15 pound, respectively. (You may find it useful to reference the appropriate table: z table or table) a. Select the null and the alternative hypotheses to determine if the machine is working improperly, that is, it is either underfilling or overfilling the cereal boxes. OHO: Ho: OHO: 1.95; HA: < 1.95 1.95; BA: > 1.95 1.95; HA: 1.95 b-1. Calculate the value of the test statistic. (Round final answer to 2 decimal places.) Test statistic b-2. Find the p-value. 0.05 p-value < 0.10 S 0.02 s p-value < 0.05 O 0.01 s p-value < 0.02 Op-value 20.10
b-2. Find the p-value. O 0.05 p-value < 0.10 0.02 s p-value < 0.05 O 0.01 s p-value < 0.02 Op-value 20.10 O p-value < 0.01 c-1. What is the conclusion at the 10% significance level? O Reject Ho since the p-value is greater than significance level. O Reject Ho since the p-value is smaller than significance level. O Do not reject # since the p-value is greater than significance level. Do not reject Ho since the p-value is smaller than significance level. O c-2. Can you conclude that the machine is working improperly? O Yes O No
