What is a non resistant measure in statistics?
The mean is called a non-resistant measure in statistics.
0.02 level of significance what is the critical value?
The critical value for a 0.02 level of significance, denoted as α = 0.02, in a statistical test corresponds to the point on a distribution that separates the critical region (rejection region) from the non-critical region. To find the critical value, you would consult a statistical table or use a statistical calculator based on the specific test you are conducting (e.g., z-table, t-table, chi-square table). The critical value is chosen based on the desired level of significance, which represents the probability of rejecting the null hypothesis when it is actually true.
Distinguish between parameteric statistics and non - parameteric statistics?
The simplest answer is that parametric statistics are based on numerical data from which descriptive statistics can be calculated, while non-parametric statistics are based on categorical data. Takes two example questions: 1) Do men live longer than women, and 2), are men or women more likely to be statisticians. In the first example, you can calculate the average life span of both men and women and then compare the two averages. This is a parametric test. But in the second, you cannot calculate an average between "man" and "woman" or between "statistician" or "non-statistician." As there is no numerical data to work with, this would be a non-parametric test. The difference is vitally important. Because inferential statistics require numerical data, it is possible to estimate how accurate a parametric test on a sample is compared to the relevant population. However, it is not possible to make this estimation with non-parametric statistics. So while non-parametric tests are still used in many studies, they are often regarded as less conclusive than parametric statistics. However, the ability to generalize sample results to a population is based on more than just inferential statistics. With careful adherence to accepted random sampling, sample size, and data collection conventions, non-parametric results can still be generalizable. It is just that the accuracy of that generalization can not be statistically verified.
What is the role of inferential statistics in business?
inferential statistics tries to infer from the sample data what the population might think. They can use inferential statistics to make judgments of the probability that an observed difference between groups is a dependable one or one that might have happened by chance in a study. Business Statistics is the science of good decision making in the face of uncertainty and is used in many disciplines such as financial analysis, econometrics, auditing, production and operations including services improvement, and marketing research. These sources feature regular repetitive publication of series of data. This makes the topic of time series especially important for business statistics. It is also a branch of applied statistics working mostly on data collected as a by-product of doing business or by government agencies. It provides knowledge and skills to interpret and use statistical techniques in a variety of business applications. A typical business statistics course is intended for business majors, and covers statistical study, descriptive statistics (collection, description, analysis, and summary of data), probability, and the binomial and normal distributions, test of hypotheses and confidence intervals, linear regression, and correlation. Role of Statistics in Economic: Economic statistics is a branch of applied statistics focusing on the collection, processing, compilation and dissemination of statistics concerning the economy of a region, a country or a group of countries. Economic statistics is also referred as a subtopic of official statistics, since most of the economic statistics are produced by official organizations (e.g. statistical institutes, supranational organizations, central banks, ministries, etc.). Economic statistics provide the empirical data needed in economic research (econometrics) and they are the basis for decision and economic policy making. Econometric: Econometrics is concerned with the tasks of developing and applying quantitative or statistical methods to the study and elucidation of economic principles. Econometrics combines economic theory with statistics to analyze and test economic relationships. Statisticians are concerned that the business world does not regard statistical literacy, or statisticians, as important. Little progress has been made in spreading the belief in the power of statistics to the non-statistical. This problem is as strong in the context of supporting organizational and product quality improvement as it is elsewhere. We summarize the effect of Genichi Taguchi's work on industrial experimentation, as well as developments in the use of statistical process control, statistical reliability requirements and other statistical approaches to quality. The effect of developments in quality systems standards, such as BS EN ISO 9000, the European Business Excellence Award Model and the Baldrige Award, are also discussed. We argue that statisticians' attitudes to non-statisticians and the use of their discipline will have to change if statistics is to realize its potential in supporting quality improvement. Re-education is necessary not just for the non-statistician but for the statistical community as well.

What does the term relative risk refer to?
In Statistics and Mathematical Epidemiology the term Relative Risk refers to the risk of an occurrence ( or evolving disease) associated to being unprotected. Relative Risk is a rate of the likelihood of the occurrence happening in the exposed group compared to the non-exposed group.
What is a non resistant measure in statistics?

Types of piping?
piping critical , non critical critical piping : where temperature ,pressure are high and sizes of pipe are big and piping connected to critical equipment( such pump,turbine compressor etc) non critical : other than criti
Difference between critical and non critical task in real time system?
the difference in critical and non critical task in a system is critical task are processes that the computer needs to operate correctly they are must have programs. Non critical talk are task that are running or can run but is not a crusial part if the task is deleted or ended then the OS should still fuction properly
What is Semaphore and state its implementation?
Semaphores are used to provide mutual exclusion and condition synchronization. Locks provide mutual exclusion and have special properties that make them useful in object-oriented programs Implementation: public interface semaphore { //creating the semaphore interface public void semWait(); //method signature public void semSignal(); //method signature } Semaphore lock = new semaphoreImplementation(1); //implementing the interface //non-critical instructions lock.semWait(); //method calling to enter critical region //access data // accessing shared data lock.semSignal(); // method calling to exit critical region //non-critical instructions
What are some characteristics of an idiom?
Idioms are expressions that have meanings beyond the literal interpretation of the words used. They are culturally specific and often closely tied to the language and region they come from. Idioms can be colorful, creative, and non-literal.

How a mutation in DNA many NOT necessarily have a bad affect on the gene's protein product?
The mutation may still code for the same amino acid, or it may cause a change in a non-critical region of the protein.
What are the most valuable non renewable resources in SW Asia?
The most valuable non-renewable resources in Southwest Asia include oil, natural gas, and minerals such as phosphates. These resources are critical for the region's economy and play a significant role in global energy markets.
