The test statistic and p-value of the given data are 6.274 and 0.0001 respectively.

<h3>Test Statistic</h3>

The test statistic can be calculated using the formula below

t = \frac{x-\mu}{\sigma / \sqrt{n} }

Solving for the mean and standard deviation, we can substitute the values into the above equation which will be

t = \frac{x-\mu}{\sigma / \sqrt{n} } = 6.274

<h3>P-Value</h3>

Using the data from the test statistic, we can calculate the p-value of the data

p-value = p(z < 6.274)= 0.0001 = 0.00

From the calculation above, the test statistic and p-value of the given data are

  • 6.274
  • 0.0001
