Formula Generator - ZTEST function

The ZTEST function calculates the probability that a sample mean is greater than a specified value, assuming a normal distribution. It is commonly used in hypothesis testing and quality control analysis.

How to generate an ZTEST formula using AI.

To get the ZTEST formula for your data, you can ask the AI chatbot the following question: "Can you provide me with the formula for conducting a Z-test in Excel?"

ZTEST formula syntax.

The ZTEST function in Excel is used to perform a one-sample z-test for the population mean. The syntax for the ZTEST function is as follows: ZTEST(array, [x], [sigma]) - array: This is the range of data values that you want to perform the test on. - [x]: This is the hypothesized population mean. It is an optional argument and if not provided, the function assumes a mean of zero. - [sigma]: This is the known population standard deviation. It is an optional argument and if not provided, the function assumes a standard deviation based on the sample. The ZTEST function returns the probability (p-value) of observing the given sample mean, assuming the null hypothesis that the population mean is equal to the hypothesized mean. Here is an example of using the ZTEST function: =ZTEST(A2:A10, 50, 10) In this example, the function performs a one-sample z-test on the range A2:A10, assuming a hypothesized mean of 50 and a known standard deviation of 10. The result is the p-value of the test.

Use Cases & Examples In these use cases, we use the ZTEST function to calculate the probability that a sample mean is significantly different from a population mean, based on a given significance level and sample data.
