(c) (3 points) What is the probability that four or more flush public toilets with their foot? - - > (d) (3 points) What is the expected number of people who will flush the toilet with their foot? (e) (3 points) What is the standard deviation of this random variable?MAT*H167: Principles of Statistics The Binomial Distribution and Continuous Random Variables 1. The Healthy Handwashing Survey conducted by the Bradley Corporation found that 64% of adult Americans operate the flusher of public toilets with their foot. Suppose that a random sample of 5 adult Americans is selected and the number who flush public toilets with their foot is recorded. (a) (4 points) Explain why this is a binomial experiment (Note: There are four conditions that must be satisfied.)> This DOES satisfy the four conditions that must be present for a binomial distribution to be present. Rationale > 1. The observations are fixed at 5. 2. Each observation(trial) will be independent of each other. 3. There are 2 possible outcomes only: flush public toilets & do not flush public toilets. 4. The probability for a 'success' or a 'failure' are the same for each individual observation. (b) (6 points) Create a probability distribution for this binomial random variable
