Q1. In a second-semester English class, 35% of the students are sophomores and the rest freshmen; 30% of the sophomores are repeating the course and 20% of the freshmen gained admission to the course by advanced placement. The professor randomly selects a student to comment on the assignment. (Round your answers to three decimal places.)

Find the probability that the professor selects a freshman who gained advanced placement admission to the class.?

A) In a group of college students, 60 males and 80 females, 25% of the males and 45% of the females are from out of state. A student is randomly selected. Find the following probabilities. (See Example 9. Round your answers to three decimal places.)

At a large university, freshmen students are required to take an introduction to writing class. Students are given a survey on their attitudes towards writing at the beginning and end of class. Each student receives a score between 0 and 100 (the higher the score, the more favorable the attitude toward writing). The scores of nine different students from the beginning and end of class are shown below. Use the Wilcoxon signed-rank test to check at a 5% significance level...
