Taguchi experiment is to be performed on the effects of lift, bore, stroke, and compression on engine performance with horsepower as the outcome variable. The factors were tested at each of the following levels in hopes of improving engine horsepower.
Lift (L) 2.75 2.90Bore (B) .10 .30Stroke (S) .50 .60Compression © 8.50 12.00
The following experiment was used and the results of all trials are as follows:

Sampling area consisted of an area of 120m x 50m within site two and was bordered by a road on one side and a stream on another.
Consider the following two columns that describe different types of data: A. Nominal 1. Qualitative B. Discrete 2. Quantitative C. Ordinal D. Continuous. The correctly paired groupings of the two columns is:
What is the value of the population mean? What is the best estimate of this value?
Suppose you, as the manager of Tennessee Grilled Pork. would like to ensure you have enough cleaning staff for your dining room and would like to analyze data for customers who enter the restaurant to place and order and either eat in the restaura..
Describe the distribution of the x-bars that you see in part b (shape of distribution, center, and the amount of dispersion).
A store selling newspapers orders only x=4 of a certain newspaper because the manager does not get many calls for that publication. If the number of requests per day follows a Poisson distribution with mean 3.
Furthermore, you could also perform a regression on the data so you have a model with which you can predict other people's IQs based on their mother's IQ.
The Daytona Beach Tourism Commission is interested in the average amount of money a typical college student spends per day during Spring Break.
One item on a questionnaire asks, "How many siblings (brothers and sisters) did you have when you were a child?" A researcher computes the mean, the median, and the mode for a set.
Stanford Binet IQ scores have a mean of 100 and a standard deviation of 15. Albert Einstein reportedly had an IQ of 160. Convert Einstein's IQ score to a z score.
Help with showing how do detrime the standard deviation of a problem when the standard deviation is 5. An example would help me to work out a problem for the normal probability distribution.
Calculate the p- value and use it to test H0 versus H a at each of a .10, .05, .01, and .001. d How much evidence is there that the mean composite satisfaction rating exceeds 42?
