## How do you find the test statistic z0?

The test statistic is a z-score (z) defined by the following equation. z=(p−P)σ where P is the hypothesized value of population proportion in the null hypothesis, p is the sample proportion, and σ is the standard deviation of the sampling distribution.

## What is the value of a test statistic?

A test statistic is the value used in a hypothesis test to decide whether to support or reject a null hypothesis. This statistic compares data from an experiment or sample to the results expected from the null hypothesis.

## How do you calculate a test statistic?

How do you calculate test statistic? The formula to calculate the teststatistic comparing two population means is, Z= ( x – y)/√(σx 2 /n1 + σy 2 /n2). Inorder to calculate the statistic, we mustcalculate the sample means ( x and y ) and sample standarddeviations (σx and σy) for each sample separately. n1and n2 represent the two sample sizes..
