5. The table below presents the joint probability distribution of reading speed (word per minute) and levels of comprehension (percent of text understood) obtained from a sample of 200 readers. 20% Comprehension 60% Reading Speed 200 400 0.05 0.05 0.03 0.30 85% 0.02 0.25 600 0.01 0.14 0.15 i. Create the marginal probability distributions from the above table. ii. Calculate the expected values and standard deviation. iii. Calculate the correlation between the two variables. Interpret your answer.
