b)) The company automatically manufacture its control boards. The quality inspector has determined that in each package, 89% of the control boards are within the correct tolerance values with respect to their functionality, the remainder were out of tolerance. If a random sample of 6 boards are drawn from the package determine the probabilities that: i) ii) ii) 3 of the sample boards are out of tolerance More than 3 of the sample boards are out of tolerance Less than three of the sample boards are out of tolerance.

b

Task 6
The company kave checked the capacitances of a batch 120 of 100 µF capacitors and given
you the results as shown in the group frequenty table 1 below.
Use that data given to calculate the mean and standard deviation of the data.
You shoutd provide clear explanation of the caleutations used and a suitably chosen graphical
-representation of your results suitable for a non-technical audience.
You may use a spreadsheet for these calculations, but you must provide clear
evidence of the formulas used in each cell and submit the spreadsheet file with your
report.
