1. | Statistical Literacy What does the expected value of a binomial distribution with n trials tell you? 2. | Statistical Literacy Consider two binomial distributions, with n trials each. The first distribution has a higher probability of success on each trial than the second. How does the expected value of the first distribution compare to that of the second? 3. Basic Computation: Expected Value and Standard Deviation Consider a binomial experiment with n = 8 trials and p = 0.20. (a) Find the expected value and the standard deviation of the distribution. (b) Interpretation Would it be unusual to obtain 5 or more successes? Explain. Confirm your answer by looking at the binomial probability distribution table. 4. | Basic Computation: Expected Value and Standard Deviation Consider a binomial experiment with n = 20 trials and p = 0.40. (a) Find the expected value and the standard deviation of the distribution. (b) Interpretation Would it be unusual to obtain fewer than 3 successes? Explain. Confirm your answer by looking at the binomial probability distribution table.
