Construct a percentage distribution using the drying- time data of Exercise 3.115.
Answer to relevant QuestionsPercentage distributions are useful in comparing two frequency distributions having different total frequencies. Construct percentage distributions from the following two frequency distributions and determine whether the ...The following are the times to failure of 38 light bulbs, given in hours of operation. (a) Dropping the rule that class intervals must be equal, construct a frequency distribution from these data. (b) Can you find the class ...The probability density of the continuous random variable X is given by (a) Draw its graph and verify that the total area under the curve (above the x- axis) is equal to 1. (b) Find P(3 < X < 5). The density function of the random variable X is given by Find P(X < 1/4 ) and P(X > 1/2). With reference to Exercise 3.34, find the probability density of Y and use it to recalculate the two probabilities. In exercise Find P(Y ≤ 5) and P(Y > 8).
