A sample of ten rates to escape time (In seconds) was: 100, 38, N, 122, 95, 116, 56, 135, 104, N Can you calculate the mean average of the sample data set? Explain

A sample of ten rates to escape time (In seconds) was: 100, 38, N, 122, 95, 116, 56, 135, 104, N Can you calculate the mean average of the sample data set? Explain. Is the median average a meaningful measure of central tendency for the data set? Explain. . Write something about the mean, median and mode averages of the life span sample of twenty refrigerators were manufactlu'ed by a company: 5, 5, 5 , 6 , 6, 6, 6, 7, 7, 7, 7, 7,7,8,B,8,8,9,9,9 A sample of the masses of 80 parcels (measured to the nearest tenth of a kilogram) is grouped in a frequency distribution: Mass (kg) Number 20.0-20.4 2 20.5-20.9 12 21.0-21.4 17 21.5213 25 22.0414 1'? 22.5—22.9 7 Estimate the mean, median and modal masses of the parcels. Which of these averages best represent the data?
