2. For the entire world's population, approximately 14% of all people speak Chinese as their native language. Suppose four people are randomly selected from the Earth's population, and define x to be the number of these who speak Chinese as their native language. The probability distribution associated with this random variable is given below. Complete the table to find the answer. (12 points) X P(x) 0 0.547 0.356 2 0.087 W 0.009 4 0.001 Totals Calculate the expected value (the mean) of this distribution. 3. Build a stem and leaf plot for the data set provided. (10 points) {78, 82, 88, 90, 90, 93, 95, 97, 102, 111, 114, 118, 120, 126} 2
