Statistical Thinking: Chapter Summary And Analysis

Due to financial hardship, the Nyke shoe company feels they only need to make one size of shoes, regardless of gender or height. They have collected data on gender, shoe size, and height and have asked you to tell them if they can change their business model to include only one size of shoes – regardless of height or gender of the wearer. In no more 5-10 pages (including figures), explain your recommendations, using statistical evidence to support your findings. The data found are below:

a. For each year, create tables of counts of gender and of nationality. Then create column charts of

The confidence interval is used as a type of interval estimate of a sample population to indicate the reliability of the

24) The cumulative probability for all six outcomes of tossing a fair die should end with the value 1.00.

19) To establish a probability distribution, the relative frequency for each possible outcome of the variable is found by dividing the frequency of observation by the total number of observations.

A listing of all possible outcomes of an experiment and the corresponding probability is called:

Discussion questions two each week: Should be responded to during the week class is in session Starting TUESDAY. (DO NOT wait till Monday the last day of any academic week to answer all the questions) P.S... Read ALL of the posts with IMPORTANT in the subject line first and follow the directions. Please put your name after the DQ in the subject line. When you respond directly to the DQ, 100 word count minimum on ALL posts.

The following formula for expected value of sample information tutor which is used to compute expected

distribution occurs so much. It is also a good way to calculate the collection of data with minimal

2. (HWK) A drug manufacturer is interested in the proportion of persons who have hypertension (elevated blood pressure) whose condition can be controlled by a new drug the company has developed. A study involving 5000 individuals with hypertension is conducted, and it is found that 80% of the individuals are able to

Bernoulli numbers evaluate the probability of a sequence of rational numbers. They’re found commonly within many types of mathematics: Number Theory, Euler-Maclaurin summation, and power series are some exampled. Once Bernoulli’s ideas were published, it gave flight to many mathematicians in the field of probability. You can consider Jakob Bernoulli as the founding father of probability.

When researching about mathematics in a medical environment, I found that one can use probability to calculate how accurate a medical test is exactly. There are many factors that play into the reason for level of accuracy of the test. Despite the fact that results will vary from laboratory to laboratory, one of the highest accuracy rates is 97%, for which was well-known and thought of as prestigious and high quality. However, this raises the point of that is essential in the understanding of the accuracy of any given diagnostic test. The accuracy of the diagnostic tests are derived from statistical distribution. However, this brings in the question according to diagnostic tests of how much error is acceptable and does the % error

I arranged all my work to their respective folders and files, read the learning guide, started the discussion and I updated the learning journal.

A confidence interval is a range within which most probable values would occur around a measurement. They are used to convey how correct an estimate of the population is, based on the sample size. By using the traditional normal based method to calculate the C.I, the degree of confidence that the population is within the range is measured as a probability; in this case 95% and 99%.

The third graph shows the hazard rate function that, as it was mentioned earlier, is a polynomial function of time to maturity and parameters λ_i for i=1,…,n. The horizontal axes shows the recovery rate values, meanwhile the
