What is the probability of a sample mean being less than 12752 or greater than 12755?
sample n equals 37 sorry and if you could write the equation that would be helpful
Why would you use a z test rather than a t test?
When the sample size is greater than 30
What is a sample size?
When something is a sample size, that means it is smaller than the size that is normally available for purchase. Sample size products are usually enough to let you try something before you buy it.
Why would having a larger sample size be a better idea than having a samll sample size when doing an experiment?
less bias and error occur when sample size is larger
A sample of 66 observations will be taken an infinite population The population proportion equals 0.12 The probability that the sample proportion will be less than 0.1768 is?
.9222
What is the sample size for standard deviation?
There is no such thing. The standard error can be calculated for a sample of any size greater than 1.
When can you estimate a population's size when counting individuals in a sample of the population?
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.

If the size of a sample equals to the size of the population?
Sample is subset of the population so sample size and population size is different.However, as a subset can be the whole set, if the sample size equals the population size, you have sampled the entire population and you will be 100% accurate with your results; it may cost much more than surveying a [representative] sample, but you get the satisfaction of knowing for what you surveyed the population exactly.Using a sample is a trade off between the cost of surveying the whole population and accuracy of the result.A census is a survey of the whole population and could be considered that the sample size = population size; in this case the results are 100% accurate.The television viewing figures are calculated using a sample of the whole population and then extrapolating them to the whole population; depending upon how the same was chosen, including its size, will affect the accuracy of the results - most likely not more than 95% accurate.With a carefully selected (that is properly biased) sample you can prove almost anything!
Will margins of error for sample of size 80 be larger or smaller than those for sample size of 40?
They should be smaller for the sample size 80.
What are the greater than equal to and less than symbols?
> is greater than = is equals < is less than.
Is 500 in greater than less than or equals to 40 ft?
Greater.
How big is feet?
24 square feet equals about 2.23 square meters. It's greater than the area of a twin size mattress but less than the area of a full size mattress.
