(Hint: Use inverse normal calculator.) The Virginia Cooperative Extension reports that the mean weight of yearling Angus steers is 1152 pounds. Suppose that weights of all such animals can be described by a normal model with a standard deviation of 84 pounds. What is the cutoff value for the highest 10% of steer weights? for the lowest 20% of steer weights? for the middle 40% of steer weights (two cutoffs)?

Let E/F be an algebraic extension. Let K and L be intermediate fields (i.e. F ⊆ K ⊆ E and F ⊆ L ⊆ E). (i) Prove that if the extension K/F is separable then the extension KL/L is separable. (ii) Prove that if the extension K/F is normal then the extension KL/L is normal. Note: To make things easier for you, you can assume that E/F is finite (hence all extensions are finite),

31. (SHORT TIME) TRUE/FALSE--A firm that employees 1st degree and block pricing strategies captures ALL consumer surplus, which leads to higher profits. 32. (SHORT TIME) TRUE/FALSE--A firm will enjoy higher profits when it utilizes 1st degree price discrimination rather than two-part pricing. Please Explain
