. Assume that 75 percent of the students at the university have taken 4 years of high school math. Of those with four years of high school math, 80 percent plan to major in science. Of those without 4 years, only 10 percent plan to major in science. You stop a student at random. If the student plans to major in science, what is the probability that this student had four years of high school math?

A different I/O psychologist wants to know if there is a difference in worker evaluations depending if the employee is a male or female.  A group of managers were recruited and each rated both 15 men and 15 women employee evaluations on a scale of 0-10.  The ratings on the worker evaluations were recorded for each manager.  Which statistical test would be best to determine if there is a significant difference between groups?     one-sample t-test     dependent samples t-test           ANOVA

Suppose a jar contains 3 blue and 5 green balls. If two balls are drawn without replacement, find the following probabilities. Enter your answers as decimal numbers with two decimal accuracy. (Hint: Draw a tree diagram) The probability that the first draw is blue and the second draw is green: The probability that the one of the draws is blue and the other is green:
