if an independent-measures study uses n = 15 participants in each group to compare two treatment conditions. then 28 is the df value for the t statistic for this study.
The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.

When a small percentage of a country does agriculture, then it indicates that the country relies heavily on food imports from other countries. If they do not grow their own, let's say, vegetables or fruits, then they have to get the necessary staple foods from imports. It will most likely also indicate that the country is trying to be more industrialized focusing more on other industries as compared to concentrating on growing food, plants, and crops. It may also indicate that the country's land is not very conducive for growing a lot of kinds of crops.
