Hypothesis Testing

Select the correct parameter and use the spaces below to compute the test statistic and P-value for a hypothesis test.

Proportion

\(p_0\): \(\hat{p}\): \(n\):

Test Stastic:

\[z = \frac{\hat{p}-p_0}{\sqrt{\frac{p_0 \cdot (1-p_0)}{n}}}\]

z = {{propstat}}

To compute relevant critical values, use this calculator.

P-values:

Left-tailed: {{propleft}}

Right-tailed: {{propright}}

Two-tailed: {{proptwo}}

\(\mu_0\): \(\bar{x}\): \(s\): \(n\):

Test Statistic:

\[t = \frac{\bar{x}-\mu_0}{s / \! \sqrt{n}} \]

t = {{meanstat}}

To compute relevant critical values, use this calculator.

P-values:

Left-tailed: {{meanleft}}

Right-tailed: {{meanright}}

Two-tailed: {{meantwo}}
