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.

She’s right it should be 2,5,4

This kind of perception involves the identification of an object through touch and exploratory procedure. The achievement of perception is through exploring the surfaces of the object which involves the spatial features.

Unconscious perception is inferred when a stimulus influences behaviors and/or neural activity
while the subject reports being unaware of it. Conscious perception<span> and attention are difficult to study, partly because their relation to each other is not fully understood. </span>
