This problem set deals with the problem of non-constant acceleration. Two researchers from Fly By Night Industries conduct an experiment with a sports car on a test track. While one is driving the car, the other will look at the speedometer and record the speed of the car at one- second intervals. Now, these aren't official researchers and this isn't an official test track, so the speeds are in miles per hour using an analog speedometer. The data set they create is: {(1,5), (2, 2), (3, 30), (4, 50), (5, 65), (6,70)} Z = 25 They notice that the acceleration is not a constant value. They decide that a fourth-degree polynomial will be the best to describe the speed of the car as a function of time. The task here is to determine the fourth-degree polynomial that fits this data set the best. 1. Construct the system of normal equations A¹ Ax = A¹b. AT A = АТЬ= 2. Solve the system of normal equations. (I don't want you doing this by hand. Use a calculator or app.) x =

In Galton’s height data (Figure 7.1, in Section 7.1), the least-squares line for predictingforearm length (y) from height (x) is y = −0.2967 + 0.2738x.a) Predict the forearm length of a man whose height is 70 in.b) How tall must a man be so that we would predict his forearm length to be 19 in.?c) All the men in a certain group have heights greater than the height computed in part(b). Can you conclude that all their forearms will be at least 19 in. long? Explain.
Answer true or false to each of the following statements and explain your answers. a. Polynomial regression equations are useful for modeling more complex curvature in regression equations than can be handled by using the method of transformations. b. A polynomial regression equation can be estimated using the method of least squares, the same method used in multiple linearregression. c. The term “linear” in “multiple linear regression” refers to using only first-degree terms in the predictor variables.
Use R functions to conduct the following 1. Calculate the following quantities: i) the sum of 80.3, 34.9 and 112.01 ii) The square root of 121 iii) 10-based logarithm of 1000, and multiply the result with the sin of 2n 2. Use the function cumsum() to calculate the cumulative sumation of the elements of the vector v = (2.3, 5.7, 1*10-7, e) 3. Calculate the cumulative sum of the previous numbers in reverse order. Hint: use the rev function 4. Assigns numbers 10 and 20 to varaibles s x and y, then write R commands for the following i) store the result of multiplying x and y in a new variable z. ii) Creat a vector My Vec of the objects x, y and z. iii) Find the minimum, maximum, length, and variance of MyVec 5. The follwing numbers are the error in measurment in an expriemnt 0.1 0.6 33.8 1.9 9.6 4.3 33.7 0.3 0.0 0.1, store them into a vector MesErr. 1) What is the mean and the standard deviation of the errores ii) which item has maximum error ii) calculate the cost of correcting the error…

Note that the equations are linear in the coefficients. Write the equations here: 2. Construct the…
A professional golfer is shopping for a new brand of golf ball. She likes most of the features of one particular brand, but she wants to make sure that the brand has a desirable spin rate (the rate at which the ball spins on its axis after being struck by a golf club). To test the spin rate of this new brand of ball, the golfer hits the brand of ball on 100 shots, and a computer measures the spin rate for each shot. The computer then produces the following histogram summarizing the 100 spin rates. Relative frequency 0.3. 0.2 0.10 0.1+ 0.09 0.0- 5000 5500 6000 0.24 0.24 0.22 6500 0.11 7000 7500 8000 Spin rate (in revolutions per minute) Based on the histogram, find the proportion of spin rates in the sample that are greater than or equal to 7000 revolutions per minute. Write your answer as a decimal, and do not round your answer. ☐ X
