Hello! Need some help after not doing so well on these practice hw problems. Thanks!!

2, 1:57 PM Quiz: BONUS Week 2 Homework (Lesson 2.6: Simulating Random Variables.) BONUS: Suppose U and V are independent Uniform(0,1) random variables. (You can simulate these using the RAND() function in Excel, for instance.) Consider the nasty-looking random variable Z = v-2ln(U) cos(2TV), where the cosine calculation is carried out in radians (not degrees). Go ahead and calculate Z. . . don't be afraid. Now, repeat this task 1000 times (easy to do in Excel) and make a histogram of the 1000 Z's. What distribution does this look like? O a. Normal O b. Unif(0, 1) O c. Exponential O d. Weibull Question 9 1 pts (Lesson 2.10: Conditional Expectation.) BONUS: Suppose that f(x, y) = 6x for 0
