1. Complete a frequency distribution tally sheet and a histogram of the measurement data given below in table 1-1.

Table 1-1 Finished length of a shaft being faced on an engine lathe. Specifications: 450.5mm
45.0	45.1	45.5	45.0	45.5	45.5	45.7	45.5	45.5	45.0
45.7	45.3	45.6	45.0	45.0	45.0	45.6	45.0	45.6	45.7
45.6	45.5	45.4	45.1	45.2	45.0	45.5	45.0	45.4	45.1
45.4	45.6	45.2	45.3	45.6	45.3	45.4	45.6	45.6	45.0
45.2	45.8	45.6	45.4	45.4	45.1	45.3	45.4	45.4	45.3

NoteYou may use a computer program to draw the histogram of the data and then insert it in your word file if you have knowledge on how to complete it. If not, completing the histogram by hand and scanning it to the computer is sufficient. Just ensure that it is neat and legible.On your histogram plot:

• Draw the lines that indicate the process capability
• Draw the lines that show the LSL and USL
• Plot a line that shows the nominal value (45.0 mm)
• Plot a line that shows the average of the process output

1a. Is the process acceptable? Why?1b. What adjustments, if any, would you make to this process to improve its performance?
