D Question 4 1 pts When deciding if the distribution of a binomial random variable can be approximated using the Poisson Distribution, all of the following must be true EXCEPT O a. n is large O b. p is small О с. npenp(1-p) d. We are modeling incidence of disease
9. The four conditions required for using a Binomial distribution are. (a) A fixed number of trials (n). b) On each trial, there are two possible outcomes, one of which we call a "success" (c) On each trial, P(success) is the same (d) The outcomes of each trial are independent For each of the following decide if the random variable defined (X) is a Binomial variable or not. If it is not a Binomial variable, say which of the four...
5) True or False: The diameters of 10 randomly selected bolts have a binomial distribution. A) True B) False 6) True or False: Suppose that a judge's decisions follow a binomial distribution and that his verdict is incorrect 10% of the time. In his next 10 decisions, the probability that he makes fewer than 2 incorrect verdicts is 0.736. A) True B) False SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. 7)...
The normal distribution can be used to approximate the binomial distribution. In order to use the normal approximation, np and nq must be greater than or equal to 5. A correction for continuing must also be used true or false
In general, the binomial probability P(X
x) is approximated by the area under the normal curve to
the right of x - .5.
True
False
Question 6. Explore the Student's t-Distribution Let us use R to become familiar with the Student's t-distribution. For that you may have to use some of the following (R-inbuilt) functions: rt (n, df) ?rt # random generator for distribution # information on rt and its inputs Take 104 samples of a Student's t-distribution with 3 degrees of freedom. Use a morm plot to test the relation to a normal distribution. Comment on your result.

Find the standard deviation for the values of n and p when the conditions for the binomial distribution are met. n = 600, p = 0.65
What are the degrees of freedom for Student's t distribution when the sample size is 25? d.f. = Use the Student's t distribution to find tc for a 0.95 confidence level when the sample is 25. (Round your answer to three decimal places.)
