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.

Answer:
Bridgett and Timothy are dealing with the crisis Generativity vs. stagnation.
Explanation:
According to Erikson's Psychosocial stages, Bridgett and Timothy are in this stage, trying to carry on their legacy through the raising of children, which is a key point to deducing that they are dealing with this particular developmental stage.
Generativity is the step one takes to give rise to a life's work, to push the next generation to continue with it.
We can see that the couple is preoccupied with the continuance of the family's ideals and values as well as tradition even when they are no longer alive.
This stage normally occurs around the age of early forties to mid sixties. It can be deduces that Bridgett and Timothy are in their late thirties and have overcome the previous stage in order to move forward to this one.
