IV. EVALUATION: In a factory, a certain part of a car is being produced, the target number of parts that should be produced in a day is 100. The quality control officer checks and records all parts that are produced in a day. The data for a 20- day production are shown on the table below. Find the average number of parts produced in 20 days. Did they meet the target number of parts that should be produced in a day? Determine the variance and standard deviation and tell if there is a big difference between the average number of parts produced to the number of parts produced daily in 20 days. 102 100 98 100 101 102 102 100 99 102 98 102 100 100 100 100 100 100 101
