Question

A Standard Reference Material is certified to contain 94.6 ppm of an organic contaminant in soil. Your analysis gives values of 98.6, 98.4, 97.2, 94.6, and 96.2 ppm. After applying the appropriate statistical t-test to confirm whether your results differ from the expected result (a = 005), the following conclusion should be drawn

The null hypothesis is accepted.

There is no evidence that your results are significantly different to the expected result.

t_calc = 3.242, the null hypothesis is rejected.

There is no evidence that your results are significantly different to the expected result as well as the null hypothesis is accepted.
