7. Among freshmen at a certain university, scores on the Math SAT followed the normal curve, with an average of 550 and an SD of 100.

Select one (1) of the scenarios and write a four to five (4-5) page paper in which you:

Use the sales forecaster’s prediction to describe a normal probability distribution that can be used to approximate the demand distribution. Sketch the distribution and show its mean and standard deviation.

13) Refer to the table. What is the average number of customers in the queue plus the number being served?

Question 27: The fact that processes tend to be dynamic, rather than static, is a key principle of statistical thinking. Which of the following is a natural consequence of this fact?

43.a) When a coin is tossed 4 times there are 16 possible outcomes and one way to roll a heads 4 times in a row. Let A represent the probability of rolling 4 heads.

3. List the probability value for each possibility in the binomial experiment that was calculated in MINITAB with the probability of a success being ½. (Complete sentence not necessary)

Then complete the following distribution tables. Please pay attention to whether you should present the results in terms of percentages or simple counts.

Sampling distribution of a sample statistics is the hypothetical distribution of the sample statistics of interest for a random sample, whereas the distribution of a sample is the probabilistic distribution of the ideas in the sample. The sampling distribution indicates how likely it is to get some definite sample when one draws a large amount of samples and the distribution of a sample shows how possible it is to get a particular data in a single random

Assume that X is a binomial random variable with n = 27 and p = 0.92. Calculate the following probabilities. (Round your intermediate and final answers to 4 decimal places.)

Repeatability: In real life, its difficult repeat the exact circumstances again, so you only get one chance to collect the results and you can’t test different ideas under the exact same circumstances. So how do you know which idea is really the best. With simulation software, you can test the same system again and again with different inputs.

5. Describe some applications from the book of the law of large numbers and the law of

5. Since the distribution D1 no longer holds, there exist a new distribution where everyone has 0.25 less than original and Wilt Chamberlain has 250,000 more than original

Experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials.

Statistical inference is the second part of statistics. Statistical inference uses the data that was gathered and organized by descriptive statistics in order to make a logical inference or conclusion. There are two branches of inferential statistics: Bayesian inference and frequency probability. Bayesian inference uses the scientific method to increase the probability that a hypothesis or theorem might be true by presenting factual information. By collecting evidence, the credibility of a hypothesis can change greatly. Evidence can be collected to prove, or disprove the hypothesis. A hypothesis that has been supported by enough evidence should be accepted as true, and a hypothesis that has been rejected by enough evidence
