Please answer number 4. Make sure to show work!? Thank you!!
Transcribed Image Text: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.
