Both questions #1(1-6) and #2 Question t. A die was rolled twice. The first time it landed on a number that we will call “x". The second time it landed on a number that we will call "y"...
I need help with Question 2, Question 3, Question 4,
and Question 5 please.
Question . A die was rolled twice、The first time it landed on a number that we will call "x" The second tme landed on a number that we will call "y" We will symbolize some events as follows: x is odd. xis a prime. y is odd. y is a prime. A: B: C: D: Express the following probabilities using the notation "p(.。.)". For example, the...
1. Saruman chooses a number of single dollar bills _ call it Z so that 2 P(Z = n)=Jp(1-2)(n/3)-1 when n is a positive multiple of 3 otherwise, where 0 〈 pく1. (Austin Ellis-Mohr suggested parametrizing this problem in terms of Z, which Austin called "the total money in the system." The book does it differently.) Saruman divides the dollar bills into three equal piles and flips a fair coin to decide in which of two envelopes _ call them...
1. If you are tossing a fair coin 4 times and X - the absolute difference between the number of HEADs and the number of TAILs, write down the pmf table for X. Find its mean and the standard deviation. [51 2. If you are drawing two cards (one-by-one with replacement), without looking, from a well-shuffled deck of 52 cards, what is the total count of the sample space? What is P(both are aces)? What is P(at least one of...
Question 5. Given sample data (x, y), and sample size n. We fit the simple regression model: and estimate the least square estimators (a) Suppose A,-1, ß,-2, and x-1. Compute у. b) Suppose S and sry 0.5, compute the R2.

Question 2 1 pts Suppose that we wish to built the following multiple regression model: Ý; = ßo + Ê, Xi1 + ,Xj2 where Y = mathematics exam score, X 1 =number of hours spent studying, X 2 =number of hours spent playing video games. Suppose we know that the number of hours spent studying is directly inversely proportional to the number of hours spend playing video games. Which of the following would be true, We cannot obtain the coefficients...
