8. MINITAB QUESTION: Suppose that X ~ B(50, 0.4). Use MINITAB to simulate 30 values of X by typing in the following commands:

MTB > random 30 c1;| SUBC > binomial 50 0.4.

(A) What percentage of your values are less than 20?
(B) What percentage of your values fall between 14 and 18 inclusive?

(C) MINITAB has a “cdf” command that computes P(X ≤ x) for each possible value of x. Enter the commands:

MTB > cdf;
SUBC > binomial 50 0.4.

Use the resulting output to compute P( X < 20) and P(14 ≤ X ≤ 18) . How do these probabilities compare to the relative frequencies you observed in parts (A) and (B)?

(D) If you simulated 1,000 values of X, how many of them would you expect to be less than 20?

Suppose that the probability that a certain experiment will be successful is 0.4, and let X denote the denote the number of successes that are obtained in 15 independent performances of the experiment. What is the probability of getting at least 12 successes experiments? What is the expected value and variance for the described distribution?

Question 8. For finding p-values, there are two approaches - bootstrap or use a distribution for the test statistic under the null hypothesis (like standard normal, T, Chi-Square, F). Using the distribution approach requires some assumptions (such as normality, or approximate normality, of the population distribution, large sample sizes, etc.) For the following testing scenarios, write down the assumptions that are needed a. Testing of equality of proportions between two categorical variables - p1 and p2. Ho: p1 = p2...

Suppose that you have programmed your computer to do the following: (i) Draw 50 X values from a uniform distribution between 10 and 20. (i.e. uniform on [10,20]) (ii) Count the number of X values greater than 18 and call this number G (iii) Divide G by 50 and call this number H (iv) Repeat steps i to iii to obtain 10,000 H values (v) Calculate the average H value and the variance of H Values Answer the following questions:...

please use minitab to solve this question The output of an extrusion process is known to have a 10% defect rate. A Six Sigma Black Belt recently made changes to the extrusion process as the result of some process analysis that was completed. 567 extrusions were collected after the changes were made and 40 were identified as defectives. Were the changes effective?
