Ear coning is simple and a safe way to remove excess wax and toxins from the inside of your ear. Ear coning is more comfortable and less invasive than conventional ear cleaning. The benefits have been documented through case histories by qualified practitioners. The benefits include improved hearing, visions, taste, smell, balance, and sharpened mental ability. Ear coning helps to detoxify sinus, lymph congestion, sore throat, earache, swimmers ear, chronic headaches and even allergies. The non-invasive coning process has been known to improve hearing, lymph circulation, and balance.
Part of the scientific research process it to provide testable hypothesis.
1. Are the claims made in the above paragraph testable?
2. Which ones are testable and which ones are not testable?
3. Select one claim and develop the null and alternate hypotheses and suggest a possible method of testing the hypothesis and measuring your concept.
A machine has three components working independently. The probability that Component A fails is 0.1, the probability that component B fails is 0.2, and the probability that component C fails is 0.3.
Let us suppose you have taken 100 samples of size 49 each from normally distributed population. Compute standard deviation of sample means if population's variance is 16. Area to left of ‘z' is 0.9976.
Determine and plot the probability mass function and probability distribution function of the contract award amount (in millions of dollars).
Let z represent the standard normal variable and suppose a value is randomly selected. Find each of the following probabilities by:
Merrill Lynch Securities and Health Care Retirement, Inc., are two large employers in downtown Toledo, Ohio. They are considering jointly offering child care for their employees.
Explain the general process and the steps included in conducting a hypothesis test? What is the difference between parametric and nonparametric hypothesis testing?
A normal population has a mean of 75 and a standard deviation of 5. You select a sample of 40. Compute the probability the sample mean is:
State the correct decision and give justification for your decision.
Explain the difference between the null and alternative hypothesis. Which one can be proven in a statistical sense?
In a certain city, 50 percent of the people consider themselves conservative (C), 25 percent consider themselves liberal (L), and 25 percent consider themselves to be independent (I).
Develop a mathematical programming model and solve. Discuss your results [total profits, total costs, etc].
The fill amount of bottle of soft drink has been found normally distribute with a mean of 2.0 liters and a standard deviation of 0.05 liters. If a random sample of bottles is selected, what is the probability that the sample mean will be between 1..
