The fall of Rome affected many people's daily lives. When Rome was pretty much it officially fell in 410. Rome brought so many civilizations together when it fell its citizens didn't know what to do. People who lived in cities fled their homes for the countryside in hope for protection while Rome was being raided; they later became serfs and peasants and worked for the landlord. People who already lived on the land had to defend for themselves, the Romans system of running water had already stopped, and life was harder to live than when the Romans were in control. Roman buildings were crumbling down to the ground and their remains were being used to make shacks. People were starving, illness was spreading, and people were dying, this went on for a couple hundred years. This time in Europe was truly dark in the beginning, but over time it grew into a lighter life. In this time castles were being built for protection from the many wars the new small kingdoms were making.

Answer:
Personal Opportunity Cost - Spare non drive time sacrifised
Social Opportunity Cost - Fuel efficiency (high pollution), Road Traffic (Congestion issues).
Explanation:
Opportunity Cost is the cost of next best alternative, foregone while choosing an alternative. Bill can commute either by bus, or by self drive.
If Bill drives his car, opportunity cost for him is - the spare time sacrifised, that he could have used while car drive in some other activity (eg reading, listening music).
Opportunity Cost for society is - the fuel utilisation & road traffic management efficiency sacrifised, by using private instead of public transport. This leads to more pollution, more congestion on roads.
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.
