1. Assume that you have applied for two scholarships, a Leadership scholarship (denoted by L) and a Merit scholarship (denoted by M). The probability that you receive a Leadership scholarship is 0.25. The probability of receiving both scholarships is 0.15. The probability of receiving at least one of the scholarships is 0.45. Write the probability statement using the events defined in the problem, e.g., P(L), P(M). Then compute the probability. Use 4-decimal accuracy when necessary. Please show steps. a) [3...

Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 26.2 with a standard deviation...
