Construct a frequency distribution of these data. Identify the class boundaries, the class marks, and the class interval.

## Answer to relevant Questions

Find the distribution function of the random variable that has the probability distribution Construct a cumulative frequency distribution using the data of Exercise 3.116. In exercise With reference to Example 3.4, verify that the values of the distribution function are given by F(x) = x2 + 5x / 50 For x = 1, 2, 3, 4, and 5. In exercise Check whether the function given by f(x) = x+2/25 for x = 1,2,3,4,5 ...Find the distribution function of the random variable X of Exercise 3.22 and use it to determine the two probabilities asked for in part (b) of that exercise. In exercise The p. d. f. of the random variable X is given by Find the distribution function of the random variable X whose probability density is given by Also sketch the graphs of these probability density and distribution functions.Post your question
