Question

weg tested for the assembly of electronic circuit boards. For A new procedure is being tested for the assembly of electronic employees, the time required to assemble a board is measure che method that has been proposed. Given the significance in testing whether the new method could ased. Person Current Proposed 70 oposed. Given the times listed in the table, use the 0.025 level easured for both the current procedure and uld be an improvement over the one currently 65 40

Answer 1

Answers table cas from the provided information, the difference (di) from the provua be obtained as: Proposed 70 yo 35 43 59 49 Current 65 Edi=19 a = Edi = 19 = 3.0 Standard deviation (su) M Eldi-a)2 (-5-3.8) +(6-38)2 = 4.97 Hypothesis can be made as .. Ho: There is no improvent over the current one. He: The new one is better. The t-value can be calculated as: t = slaitt fin 3.8 = 1.709 4.97/15 The t critical realue at (5-1=4) degree of freedom with 10.025 level of significance from the t- realue table is 2.776. The calculated realue is less than the critical value. Therefore, we do not reject the null hypotheses. And it can be conclude that there is no improvent over the current one.
