Question 2 Not yet answered Marked out of 4.00 F Flag question Question 3 Not yet answered Marked out of 3.00 F Flag question Question 4 Not yet answered Marked out of 1.00 F Flag question What is the value of the test statistic? Express your answer in 4 decimal places Answer: What is the pvalue. Express your answer in 4 decimal places. Answer: Select the correct decision 0 a. pyalue is less than alpha, reject the null hypothesis. 0 b. pyalue is less than alpha, fail to reject the null hypothesis. 0 c. pyalue is larger than alpha, reject the null hypothesis. 0 d. pyalue is larger than alpha, fail to reject the null hypothesis. Question 5 Select the correct conclusion Not yet answered O a. Yes, the data provides enough evidence to conclude that the new machine packs Marked out of faster. 1.00 Flag question O b. No, the data does not provide enough evidence to conclude that the new machine packs faster. Question 6 Find the 95% confidence interval of the difference in mean time to pack each carton between Not yet the new and old machine. answered Enter value of the lower bound here. Express answer in 2 decimal places. Marked out of 1.00 Flag question Answer: Question 7 Find the 95% confidence interval of the difference in mean time to pack each carton between Not yet the new and old machine. answered Enter the value for the upper bound here. Express answer in 2 decimal places. Marked out of 1.00 Flag question Answer:Question 1 A company bought a new machine that pack jars into a carton because supposedly it packs Not yet faster, on average, than the machine currently used. To test that hypothesis, they had each answered machine pack 10 cartons and recorded how long it took (in seconds) to pack each carton. A Marked out of summary of the results are shown in the table below. Assume the packing times are normally 1.00 distributed and the population standard deviations are approximately equal. Flag question Old Machine New Machine Sample mean (in seconds) 43 42.4 Sample standard deviation 0.90 0.70 Does the data provide enough evidence to conclude that the new machine packs faster, on average? Test the hypothesis at the 5% level of significance. Note: the above information is applicable to all questions below. Select the correct null and alternative hypotheses. O a. Hold= 0 HA:Md 0 O d. Ho:Hnew - Hold= 0 HA: Hnew - Hold 0 Of. Ho:Hnew - Hold= 0 HA: Hnew -Hold * 0
