Show me the steps to solveTask $2$:

Further to your discussion in task $1,$ you will complete the below practical to highlight the effects of implementing a

quality control tool.

A company manufactures electronic circuits in batches of $100.$ Each circuit is tested by QC for the current drawn when

connected to a constant voltage. The acceptable limits for the current drawn is between $41-70mA,$ any circuits that

do not fall within the limits will have to be scrapped. The typical test results pre and post the introduction of QC are

shown in table $1\mathrm{.}1$ below.

a$)$ Produce a graphical presentation of the data shown in Table $1\mathrm{.}1$ to illustrate the effects of adopting a culture of

quality control.
