Kindly Solve all questions.

This question is related to a "Research" course im taking. my research question is "How does social media impact mental health?" thats all i have regarding the research JUST the question.

The assignment question is as follows:

"Identify a DATA-MINING TECHNIQUE that could be useful for your research (stated above) AND describe it in the context lf your research. this should be between

to repeat I havent done anything besides come up with the research question, feel free to use whatever idea regarding my research question to answer the assignment question.

if you require more info please ask!

P(Senior) = 22% P(Statistics Class) = 7% P(Senior and Statistics class) = 4% 4. What is the probability that a student is a Senior, but not in Statistics class? 5. What is the probability that a student will be a Senior or in Statistics class? 6. Given that a student is in a Statistics class, what is the probability that he is also a Senior?PROBABILITY AND STATISTICS Every year more than the average 4 magnitude earthquake in Turkey is 26.Next month in Turkey Calculate the probability of not having earthquakes with magnitude more than 4. Suppose that 85.4%% of CSU students are right-handed. Of those that are right-handed, 35%% enjoy studying Statistics and of those that are not right-handed, 20.056 do not enjoy studying Statistics Round all answers in this problem to four decimal places. (a) (2 points) Calculate the proportion of CSU students that enjoy Statistics, (b) (2 points) Calculate the probability that a CSU student is right-handed and that they enjoy studying Statistics. (:) (3 points) Given that a CSU student enjoys studying Statistics, what is the probability that they are right-handed. (d) (3 points] Suppose a random sample of three CSU students is collected. What is the probability that two of the three students are right-handed20. Probability-weighted means and standard deviations The previous section discussed calculating descriptive statistics using "ex post" (historical) data. This method is effective for describing past events. In addition, you can use historical results to characterize future events-that is, if you can reasonably assume that future events will resemble past events. However, if a reliable probability distribution is available, you can calculate expected descriptive statistics (also called "ex ante" statistics). The probability distribution describes all the possible outcomes a variable can assume. Using probability data, you can calculate the expected mean, variance, and standard deviation using the following formulas: = 2p. X. i . 1 E P. ( x, - " )' 0 = Vo A probability distribution for five possible market conditions is shown below, along with the expected demand in each state. Calculate the expected value (mean) and standard deviation of demand
