According to the normal probability distribution 95 percent of the values of a normal random variable are contained w in plus or minus how many standard deviations from the mean Why is that important?

Approximately 2 standard deviations (1.96, actually) from the mean. That is important to know that if one has a sample of 1000 values, if one selects a threshold at +/- 2 standard deviations from the mean, then one expects to see about 25 values exceeding those thresholds (on each side of the mean)

What is the probability that the vowel is before j?
The answer depends on what language you refer to. It also depends on which particular vowel is being referred to as "the vowel".Then you would need to know the number of words in that language that contained a j as well as those that contained a j after the vowel. The second number divided by the fist would give the required probability.
What does interpreting data from a bar graph mean?
Determining what information about the variable is contained in the bar graph.

The purpose of statistical inference is to provide information about the?
The purpose of statistical inference is to obtain information about a population form information contained in a sample.
What is the use of data verification in database?
A database is only as useful as the data contained within it. Without data validation, inaccurate, invalid, obsolete or inconsistent data can be stored within the data tables leading to problems when the data is queried and analyzed.
Why is population distribution not uniform all over Nepal?
In probability theory and statistics, the continuous uniform distribution or rectangular distribution is a family of symmetric probability distributions such that for each member of the family, all intervals of the same length on the distribution's support are equally probable. The support is defined by the two parameters, a and b, which are its minimum and maximum values. The distribution is often abbreviated U(a,b). It is the maximum entropy probability distribution for a random variate X under no constraint other than that it is contained in the distribution's support

What is Linux Blue Cat?
BlueCat Linux is a distribution aimed at embedded systems (self-contained devices). Typically, you would find this distribution used in devices like MP3 players, print servers, etc., and would not be installed on your computer for general use.

Assume that life expectancy in the us is normally distributed with a mean of 73 years and a standard deviation of 9 years what is the probability that you will live to be over 100 years old?
You would have about 1/2 of 1 % chance of living to 100 since age 100 is three standard deviations (SD) from the mean. If you are with in three SD of the mean you have 99% of the data set or probablity contained. Hence, you would be missing 1% of which half would be above age 100 and half would be below (73-27) age 46.
The majority of the water distribution on earth comes from groundwater ice rivers and lakes?
The majority of water distribution on earth comes from ground water, river and lake. The walker also comes from oceans.
HOW Many side does a oxygen have?
None. Oxygen, as a gas, will occupy any shape that the gas is contained in. Oxygen as a single atom does not have a specific shape since its electrons do not have exact positions - only a probability space.
What types of chemicals are contained in chemical storage buildings?
Chemicals contained in storage buildings are generally those that are controlled substance or hazardous materials. They should be handled with care and stored according to regulations for safety reasons.
What does Biosphere mean according to science?
The biosphere refers to the life inside a contained area. For example, a terrarium has a biosphere composed of the soil (and the microbes and insects contained in it), the plants, the life in the water (plankton, zoophytes), the microbes in the air, etc. In the largest sense, it describes all of the life contained on Earth.
