5. Which of the following is not a condition of the binomial distribution? a) Only 2 possible outcomes b) Have a constant probability of success c) Must have at least 3 trials d) Trials must be independent

A sampling distribution contains four possible values for the sample means.  Three of the four probabilites are 0.17, 0.3, and 0.3. The remaining probability a) is 0.17 b) is 0.43 c) is 0.23 d) cant be determined without knowing the sample size

A student randomly guesses at four multiple-choice questions. Each question has three possible choices. The random variable X denotes the number of correct answers. This experiment can be modeled as Oa) a normal experiment with mean 4 and standard deviation 1/3. O b) a normal experiment with mean 1/3 and standard deviation 4. O c) a binomial experiment with 3 trials and success probability 1/4. O d) a binomial experiment with mean 4 and standard deviation 1/3 O e) a binomial experiment with 4 trials and success probability 1/3.

Nine percent of all men cannot distinguish between the colors red and green. This is the type of color blindness that causes problems with traffic signals. If six men are randomly selected for a study of traffic signal perceptions:   a)Let X = the number of men that cannot distinguish between red and green Decide if X is a binomial random variable or not (check the conditions for the binomial setting). b)Write the probability distribution of X C)Find the probability that exactly two of the six men cannot distinguish betweenred and green.
