An experiment involves selecting a random sample of 256 middle managers for study One item of interest is annual income The sample mean is computed to be 35420 and the sample standard deviation is 205?

The deviation would be how much off it would be off. Since this is a sample, it is impossible to get completely accurate results.

How are experimental probability and theoretical experiment alike?
They are both estimates of the probability of outcomes that are of interest. Experimental probabilities are derived by repeating the experiment a large number of times to arrive at these estimates whereas theoretical probabilities are estimates based on a mathematical model based on some assumptions.
Kevin recorded the effects of violent video games on antisocial behavior. Which of these is a response variable?
Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables. Antisocial behavior
What does events are mutually exclusive mean?
Two events are mutually exclusive if the occurrence of one event implies that the other cannot occur. There is no need for either to occur.For example, if you roll a die and the two outcomes of interest are:A - you roll a primeB - you roll a compositethen A and B cannot occur together. Of course, you could roll a 1, so that neither A nor B occurs.An example of events that are not mutually exclusive is:A - you roll a primeC - you roll an even numberIf you roll a 2 then both A and C occur.
What would one million dollars be worth at 5 percent interest after 75 years?
Interest = Principal x Rate x Time (years) = $1000000 x 0.05 x 75 = $3750000 $3750000 + $1000000 = $4750000 Answer: $1M will be $4.75M at 5% interest after 75 years
What is a set percentage of the deposit amount that will be given to the depositor?

The number of times interest charges are earned is computed as?
Type y income before income tax plus interest expense, divided by interest expense our answer here...
Why use standard deviation in psychology?
Measurements of the variable of interest will differ between subjects. As a result the outcome of an experiment may be different from what was expected. The psychologist will want to know whether that difference is purely the result of random variation between subjects or if it is due to some other factor. The standard deviation is a measure for determining how large a difference might be purely random.
What is A factor of interest in an experiment that is expected to change in response to another factor of interest?
Variable
How much interest will you earn in a year on 1000000 at 5 percent per year?
It would be $50,000 if it is computed once a year.
In an experiment the factor of interest is called?
D. Variable
An initial 500 compounded for 1 year at 6 percent?
Interest earned is computed by taking the principal amount and multiplying it by the rate and time and divided by the time taken. The interest in this case is 30.
What is the carrying value of a long term note payable?
Is computed as the future value of all remaining future payments, using the market rate of interest.
How can you show that more interest is paid at the beginning of a loan period than at the end?
Interest is computed on the remaining balance monthly..If you have a credit card balance and pay exactly every 30 days, you will see that the interest charged is reduced by a small amount every month.
What are the factors to consider when selecting a credit card?
There is a few things to consider when selecting a credit card. The main things to consider would be interest rates, reviews on the company and what you are wanting to use the card for.
What is the formula for Present Value Interest Factor?
Present Value Interest Factor, abbreviated as PVIF and is used to simplify present value computations, may be computed as follows: PVIF = 1 / ( ( 1 + r) ^ t) where... r = interest discount rate t = number of periods
How standard deviation and Mean deviation differ from each other?
There is 1) standard deviation, 2) mean deviation and 3) mean absolute deviation. The standard deviation is calculated most of the time. If our objective is to estimate the variance of the overall population from a representative random sample, then it has been shown theoretically that the standard deviation is the best estimate (most efficient). The mean deviation is calculated by first calculating the mean of the data and then calculating the deviation (value - mean) for each value. If we then sum these deviations, we calculate the mean deviation which will always be zero. So this statistic has little value. The individual deviations may however be of interest. See related link. To obtain the means absolute deviation (MAD), we sum the absolute value of the individual deviations. We will obtain a value that is similar to the standard deviation, a measure of dispersal of the data values. The MAD may be transformed to a standard deviation, if the distribution is known. The MAD has been shown to be less efficient in estimating the standard deviation, but a more robust estimator (not as influenced by erroneous data) as the standard deviation. See related link. Most of the time we use the standard deviation to provide the best estimate of the variance of the population.
How did Newton's interest in alchemy further his work in physics?
Newton's work in physics was based on his interest in alchemy. That interest led him to experiment and in doing so, it resulted in his discoveries about physics.
