The following are the number of highway accidents reported on 30 successive days in a certain county:
Construct a frequency distribution of these data. Identify the class boundaries, the class marks, and the class interval.
Answer to relevant QuestionsFind 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.
