What is the hypothesis in vis scenario? John wants to see it the current procas takes longer than the neve process is developing. Wan that being set-Ouerst - Now: Null Hypothesis): the current process takes less than or equal amount of time compared to the new process Alternative Hypothesis the canent process takes more time than the process Did the new oil charge process take less or more time? How do you know? Looking at the mean the new process average is lower than the current process. Additionally if you analyze the p-value and the t-stodist, which is discussed further down there is evidence to reject the rull hypothesis that the current process takes less time than the new process. In the scenario, did you conductae or two-tailed test? Aone cailed test was used since we only orted to know if the current process took out than the new one. In composer, John wanted to see terew process changed the amount of time in any sachmamer, whether longer or shorter a two-tied test could be used What is the p-value? Remember to interpret what the E-05 means and round to 3 decimal places 05 can be send an abbrisation for 10 Is this case 9.371970-05 also equals 9.37197 10. Using calculator or basic math this comes out equal 00000937197. This Palue is estremely low which is used to help us decide whether or not to reject the null hypothesis Do you think (as John does) that the result is not statistically significant? Results are considered to Stativically significant if there all be the predetermined significance level In other words, if P-value ertical cafe One ded), ther have dance to reject the aul hypotas his case, 4.520 > 1.720 we have further evidence to reject the null hypothesi Do the "peanything? Given the extremely smallp-value, there is cedence to reject the null hypothess Conclusions are decisions should not be solely based on these kind of tests. The p-value should never serve as a make or break in a decision or conclusion the p-value simply provides the evidence to reject the daim that the current oil change process takes less time than the current process. It coes not prove the claim false
