Empirical Variance of a Data Set in a Given Direction 0/3 points (graded) Consider the statistical set-up from the previous problem. In particular, recall that $u = \frac{1}{\sqrt{5}}(1, 2)^T$ and $X_1 = \begin{pmatrix} 1 \ 2 \end{pmatrix}, X_2 = \begin{pmatrix} 3 \ 4 \end{pmatrix}, X_3 = \begin{pmatrix} -1 \ 0 \end{pmatrix}$. Observe that for $i = 1, 2, 3$, the number $u \cdot X_i$ (where $u$ is a unit vector) gives the signed distance from the origin to the endpoint of the projection $proj_u X_i$. By signed distance, we mean that $|u \cdot X_i|$ is the length of $proj_u X_i$, and $u \cdot X_i > 0 \implies X_i$ points approximately in the direction of $u$ $u \cdot X_i < 0 \implies X_i$ points approximately in the opposite direction of $u$ Compute the empirical variance of the data set $u \cdot X_1, u \cdot X_2, u \cdot X_3$. 52/75 Let $X$ denote the matrix whose $i$-th row is $X_i^T$. Recall that $S = \frac{1}{3} X^T (I_3 - \frac{1}{3} 11^T) X$ denotes the empirical covariance matrix of our data set. What is $u^T S u$? (You are encouraged to use computational software.) $-3/(5\sqrt{5})$ Are your answers from part 1 and part 2 of this question the same? Yes No

Give the type of balance the cylinder is in. The roller floats in water with the density $\rho_{H_2O}$[kg/m³]. Take for calculations: H = (0,1 + 0,1 \cdot Nr)[m] = D = 1[m] d = 0,5[m] $\rho$ = 800 [kg/m³] $\rho_{H_2O}$ = 1000 [kg/m³] Results: h = [m] m = [m] kind of balance: Calculations:

In HTML and JavaScript, please! There is no starter file. Task #3 Guessing Game: We will create a program where the computer will pick a random number, and the user will try to guess the random number with feedback from the computer. It will work like this: 1. Have the computer generate a random number between 1 and 100. 2. The computer should then prompt for a number between 1 and 100. The computer should check to ensure that the number entered was a valid number and was between 1 and 100. 5. If the guess entered by the user is the computer's number, the computer will tell the user that they guessed correctly and the game stops. 6. The computer will ask for up to 6 guesses. If you do not guess correctly after 6 guesses, the computer wins. 7. The computer should store each guess in an array. After the game is complete, regardless of who wins, you should print out all the guesses in the array. Important hint: You should use a variable to keep track of the computer's number. The starter code provided has a method to create a random number when you pass it the minimum and maximum numbers in the guess range. It also has all the code for prompting the user. You are responsible for creating an array to store up to 6 guesses, creating a loop to guess up to 6 times (and storing the guesses in the array), determining if the user's guess is correct, too low, or too high, and then printing out the list of guesses that were made at the end of the game. Remember, since the computer's number is random, your output will not be the same each time.

(3 points) Elite Gymnastics, Men - After the 2004 Olympic games, the scoring system for gymnastics was overhauled. Rather than rank performances from 0 points to 10 points as the old system did, the new system judges routines based on a combination of the difficulty of the skills attempted in the performance and the gymnast's execution of the skills. Male gymnasts compete on six different apparatus, Vault, Floor, Rings, Pommel Horse, Parallel Bars, and Horizontal Bar. The values given in this problem were calculated from the reported results of international competitions of male elite gymnasts between the years 1999 and 2019. Under the old scoring system (last used in 2005), scores on the Parallel Bars apparatus had a mean of 9.185 and an sd of 0.493. Under the new scoring system (first used in 2006), scores on the Parallel Bars apparatus had a mean of 14.729 and an sd of 0.778. Round all calculated answers to 4 decimal places. At the 2005 Gymnastics World Championships under the old scoring system, Sami Aalto from Finland earned a score of 8.262 on Parallel Bars. At the 2019 Gymnastics World Championships under the new scoring system, Nestor Abad from Switzerland earned a score of 13.766 on Parallel Bars. 1. What is the z-score for Sami Aalto on Parallel Bars in 2005? z = 2. What is the z-score for Nestor Abad on Parallel Bars in 2019? z = 3. Based on the z-scores, which gymnast had a higher score, relative to the other gymnasts who competed under the scoring system used in their competition? A. Sami Aalto B. Nestor Abad C. The gymnasts scored equally well
