Certain memory chips are made from silicon wafers. The wafers
are routed through machines in an order that is referred to as a
recipe. The wafers may go through the same machine several times as
the chip is created. The data given below is a sample of processing
times, measured in fractions of hours, at a particular machine
center for one chip recipex
(a)
Sample size: n =20
The 20th percentile will be
Since 4th data value is 0.27 and 5th data value is 0.29 so required percentile is
Answer: 0.274
(b)
Mode is data value with highest frequency. So mode is 0.48.
(c)
There are 20 data values so median will be average of 10th and 11th data values. That is median is
