A local grocery store has asked you to examine the probability of choosing a product based on the height of the shelf where the product is placed. The random variable X is the height of the shelf from the floor. The customers' choice of products is defined by the probability distribution below. Complete parts (a) through (c). 0-20 20-40 40-60 60-80 80-100 Height(x) Probability (Px 0.07 0.12 0.21 0.36 0.24 a. What is the cumulative probability distribution of X? Calculate the cumulative probability distribution, F(x). Assume that the class intervals for the height are represented by variable X where X ranges from 1 to 5 for the 20 cm intervals starting at 0-20 cm through 80-100 cm, respectively. ecimals.) 1 2 3 4 5 (Type integers or Х Probability (P х F(x) 0.07 0.12 0.21 0.36 0.24 0.07 0.19 0.40 0.76 b.
