Question
C. you work as a procurement engineer in a company that produces electronic device; your manager asked
you to measure a sample of 50 resistors from a batch, which the supplier claims that are all 10K2. The
data measured is displayed in a frequency distribution as follows:
Resistance (R) KQ
frequency
9.6 <R<9.7
9.7 <R<9.8
9.8 <R<9.9
5
9.9 <R<10
17
10.0<R<10.1
18
10.1 <R<10.2
5
10.2 <R<10.3
10.3 <R< 10.4
After making the measurements, you manager asked you to perform several tasks:
1. Calculate the mean and standard deviation of the measured data.
2. Draw a histogram and a frequency polygon for this data.
3. Based on what you found in 1 & 2, write down a paragraph consisting of 4-5 lines maximum,
explaining this statistical data to a customer who has no technical background. Do not expect
the customer to understand what terms like mean, standard deviation, frequency polygon and
histogram mean.
