. Using the p=.80 . A survey from Veterinary Research Unlimited found that 80% of dogs do not have chronic ear infections. If 1000 dogs are selected at random, find the probability that::

a. Can you use a normal approximation to a binomial distribution? Yes or no -

b. How can you tell?

c. Find the probability that at most 790 will not have chronic ear infections.

d. Find the probability that exactly 800 will not have chronic ear infections.

e. Find the probability that at least 805 will not have chronic ear infections.

Please show all work or if you used a TI 84 please explain the necessary steps to get the answer, thank you for the help :)

The Higher Education Research Institute at UCLA collected data from 203960 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.5% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick 8 first-time, full-time freshmen from the survey. You are interested in the number of these 8 that believes that same sex-couples should have the right to legal marital status. 1. Idenitify...

Problem 1: Relations among Useful Discrete Probability Distributions. A Bernoulli experiment consists of only one trial with two outcomes (success/failure) with probability of success p. The Bernoulli distribution is P (X = k) = pkq1-k, k=0,1 The sum of n independent Bernoulli trials forms a binomial experiment with parameters n and p. The binomial probability distribution provides a simple, easy-to-compute approximation with reasonable accuracy to hypergeometric distribution with parameters N, M and n when n/N is less than or equal...
