♦ Notes:   Midterm II (Ch 5-12): November 11; please, check the calculator rules, below. Do not bring the wrong calculator and risk an adverse result to your performance because of it.
♣ Homework  Only hard copies of homework are received & graded. Emailed documents are not accepted unless authorized by the professor.
Assignment 9: Ch. 13  Ex. ... ; Nov 18 Please show section Notation/Definition: the expression Y~N(7,2) is short for "the random variable Y has a normal distribution with mean 7 and standard deviation 2". Pr(1<Y<2) means "the probability that the random variable Y takes on any value between 1 and 2". Pr(Y<2) = probability that the random variable Y is less than 2; (For continuous distributions (i.e., density functions like the normal), the symbol "<" can be replaced with "<" without altering the value of the result). When tackling problems like these, always draw a detailed sketch of the relevant segments of the normal distribution. Your performance on the final exam, among other things, will depend on your ability to handle such problems, so give them the effort & attention they deserve. Exercise G1: (I) If Y~N(0,1), find (a) Pr(-1<Y<1); (b) Pr(Y<-2); (c) ;Pr(Y<1) (d) Pr(-2<Y<1); (e) Pr(1<Y<3) (II) If Y~N(0,1), find (a) Pr(Y<-2.3); (b) Pr(Y<0); (c) Pr(-2.3<Y<0) (III) If X~N(1,1), find (a) Pr(X<2.3); (b) Pr(X>1.3); (c) Pr(1.3<X<2.3); (d) Pr(X<1.3 or X>2.3) (IV) If X~N(1,2), find (a) Pr(0<X<4); (b) Pr(-3<X<3) (V) If X~N(9,2), find Pr(X is more than 2.5 std deviations away from the mean) (VI) If X~N(9,2), find Pr(X is more than 3 units away from the mean) (VII) If X~N(30,5), state the 5-number summary of 1000 observations (round to nearest integers)         (Hint: assume that all data is within an interval of 6 standard deviations)

Calculator rules strictly enforced during exams:

•  Use a calculator with only the basic functions/operations: +, - , x, /, 1/x, square root. More advanced calculators, PDAs, cell phones, laptops, etc. are strictly NOT ALLOWED; their use may subject you to serious penalties! NO EXCUSES FOR HAVING THE WRONG CALCULATOR! •  CLOSED BOOK & NOTES. All necessary tables (& correlation formula) will be provided. •  Bring your Rutgers picture ID to all examinations! •  Pre-assigned seating: Look for your seat number & location; lists will be posted at the entrance. Write down your seat number before you enter; you'll need to write it on your exam paper, too.
