The lifetimes (in units of 10³ seconds) of a sample of electronic com- ponents tested to destruction are shown in 'Dataset1'. 1. Draw a frequency polygon, histogram and cumulative frequency polygon for the data. 2. Calculate the frequency mean, the frequency standard deviation, the median and the first and third quartiles for this grouped data.
