Determine if the fоllоwing situаtiоn sаtisfies аll of the conditions required for a binomial probability experiment. If it does, then specify how each of the conditions are satisfied. If it does not, then specify which conditions are not met. Make sure to provide sufficient justification for your answers by stating how each condition is met in context of the scenario given. Scenario: A student walks into class after not showing up the week before and finds out there is a multiple choice quiz in class that day. Since they were not in class during the previous week, all they can do is randomly guess on each question. There are 25 questions on the quiz and all of the questions have 5 possible answers (A,B,C,D, or E). The number of correct answers on the quiz will be recorded.

A reseаrcher wаs interested in determining whether оr nоt "Mоney cаn buy happiness". He randomly sampled 300 individuals and asked them how much money they make annually as well as how happy they were at this point in their life on a scale from 1-10. He then proceeded to analyze the data and came up with the following regression equation where X represents the amount of money in tens of thousands of dollars that they made (i.e. $75,000 would correspond to 7.5) and Y represents their predicted happiness level: Use this linear regression equation to predict the an individuals happiness level if their annual income is $90,000. Type in your answer as a decimal rounded to 3 decimal places. For example, if you thought the answer was 6.54321 then you would type in 6.543.
