Construct a percentage distribution using the drying- time data of Exercise 3.115. In exercise Unequal class intervals. The small number of observations greater than 7 in Exercise 3.119 may cause some difficulty in constructing a frequency distribution. To keep class intervals equal, one is faced with the dilemma of ...Find the distribution function of the random variable X of Exercise 3.17 and use it to reevaluate part (b).
