A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean course-testings score on the previous three tests. She then asked them to rate how likely they were to cheat on an course-testings if the opportunity presented itself with very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat.

More than three-quarters of the nation's colleges and
universities now offer online classes, and about 23% of college
graduates have taken a course online. 39% of those who have taken a
course online believe that online courses provide the same
educational value as one taken in person, a view shared by only 27%
of those who have not taken an online course. At a coffee shop you
overhear a recent college graduate discussing that she doesn't
believe that online courses provide the same educational value as
one taken in person. What's the probability that she has taken an
online course before? (Round to four decimal places if
necessary.)

(a) Calculate the cost of the ending inventory and the cost of goods sold for each cost flow assumption [LIFO,FIFO], using a perpetual inventory system. Assume a sale of 570 units occurred on June 15 for a selling price of $8 and a sale of 600 units on June 27 for $9. (Note: For the average-cost method, round unit cost to three decimal places.)

You are considering how to invest part of your retirement savings. You have decided to put 500,000 into three stocks:
51% of the money in GoldFinger(Currently $27/share), 17% of the money in Moosehead(currently $98/share), and the remainder in Venture Associates(currently $5/share). Suppose GoldFinger stock goes up to $39/share, Moosehead stock drops to $64/share, and Venture Associates stock rises to $19 per share.
