Suppose that about 85% of graduating students attend their graduation. A group of 25 graduating students is randomly chosen Part(a) in words, define the Random Variable X the number of graduates O the number of graduating students that are not attending graduation the number of graduating students that attend graduation the number of people attending graduation Part (b) List the values that X may take on OX1,2,3,..., 83, 84, 85 OX= 1,2,3..... 23, 24, 25 OX-0,1,223, 24, 25 OX=0.1.2., 83, 84, 85 Part (c) Give the distribution of X *-(0) Part (0) How many students are expected to attend their graduation? (Round your answer to the nearest whole number) students Part (0) Find the probability that 18 or 19 altend. (Round your answer to four decimal places.) Part Based on numerical values, would you be surprised al 25 attended graduation? O Yes. The probability of all 25 students attending graduation is small loss than 5%) No. The probability of all 25 students attending graduation is large (more than 10%).
