Operations Manager in an automobile assembly plant wants to reduce the time a process takes to assemble a part. Study team collects data and determines that the assembly times are normally distributed with a mean (u) of 75 seconds and standard deviation (o) of 6 seconds. Use the Z table to answer the following questions. To receive full credit, you need to show your work of applying the standardizing formula, and include one graph in the original variable and one graph in Z as illustrations for each question. Extra point if you can use symbols correctly. (i). What proportion of assembly times are more than 80 seconds? (ii). What proportion of assembly times are between 70 and 80 seconds? (iii). What assembly time is the lower limit of the 1% slowest times? (Note: faster time means smaller value) B I U I E x x, E E 12pt A A Paragraph fx
