While producing 500 electric lamps, 29 were found defective. If the daily production rate of the factory is 2 000 electric lamps, find the number of the non-defective units in a day.
Step 1: Use the sample to find the probability that a shirt is
Divide the number of non-defective units in the sample by the
number of units in the sample.
Step 2: Find the expected number of non-defective units in a day.
Multiply the total number of units produced in a day by the
probability that a unit is non-defective.
