- What is the probability that a randomly selected participant tasted apples and preferred non-organic?The expected value of a discrete random variable always corresponds to an actual outcome that may occur.An observer stands at a highway overpass and counts the automobiles that pass by. When he sees a red automobile, he stops counting. What is the likelihood that 10 automobiles will be spotted if the probability of red cars is 0.20?
- What is the relationship between the joint probability and marginal probabilities of two independent events?In a recent year, the Better Business Bureau settled 75% of complaints they received. You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Suppose your sample size is 171. What is the probability that the sample proportion will be at least 4 percent more than the population proportion?Dr. Verde conducted an experiment in which she randomly assigned each subject a colored pencil and then asked them to choose their favorite color. Her results showed that neither the distribution of the assigned pencil colors or the subjects' preferred colors conformed to their expected theoretical probability values. If she repeats the experiment with a much larger sample, how would you expect her results to change and why? Answer in complete sentences. UPLOAD
