**How do I calculate P-value based on mean and standard**

Because the population is large, we usually cannot hope to calculate the parameter of interest (e.g. the population mean) exactly, because to do so we would have to obtain income information from the large population. This is often infeasible due to costs or practicalities.... If you want the tool to calculate these for you from raw values, please select the checkbox below. To use this calculator, just input your population mean, population variance, sample mean and the number of individuals in the sample into the text boxes below.

• If we had wished to obtain a 90% or a 99% CI for the mean, then the corresponding t−values (from the table) would have been 2.132 and 4.604, respectively (see Table C.2)....

## How To Find The Population Value From A Mean

In the case of a hypothesis test for the population mean, the test statistic turns out (under certain conditions) to be a z-value (a value from the Z-distribution). Then you can look up your test statistic on the appropriate table (in this case, you look it up on the below Z -table), and find the probability that results more extreme than those found in your sample could have been found.

- So, if an observation is 1.645 standard deviations from the expected value, it is in the top 2.5 percentile of the population of interest. 2-sided refers to the direction of the effect you are interested in.
- There are two types of mean, i.e. sample mean and population mean, which is often used in statistics and probability. The sample mean is mainly used to estimate the population mean when population mean is not known as they have the same expected value.
- Calculate estimate: Estimate the population parameter—in this case, the population mean—by use of a statistic, which in this problem is the sample mean. This involves forming a simple random sample from the population.
