Uni has ruined me :( here is what I gotta do, but I have no clue how to do it
STAT251 in 2016 had 280 students enrolled in Week 1. Assume that those taking it had the same overall propensity for IBD as the rest of Australia, and let X be the number (among those 280) with IBD. Use the Poisson distribution to answer the following questions: What is the expected value of the number of students with IBD? (1 mark) What is the standard deviation of the number of students with IBD? (1 mark) What is the probability that there were fewer than 2 students with IBD? (2 marks) What is the probability that there were more than 3 students with IBD? (2 marks) --- "Just play at your own pace, you can only play blind once!" ~ Vascela Jiggly since N64 ...
