Step-by-step explanation:

In an independent groups experiment, if we must estimate the population standard deviation to determine the significance of the sample results, the appropriate inference test is the<u> </u><u>t test</u>

A t-test is one of the methods of a statistic and is used to determine if there is a significant difference between the two groups of their means based on a sample in data.
The statistical significance is determined by the difference between the averages of group size , the sample size, and standard deviations of the groups.

<h3>Therefore option c) t test is correct</h3>
