- Linear Algebra This problem was rejected a few minutes ago. I know and understand Bartleby's honor code. This problem is part of a midterm I have already submitted this morning. I want to ensure my answer is correct, mostly because I was not able to complete part (d) due to the time limit. Per my honor code I would not ask for assistance on a graded problem. I am including my submission. If you would kindly verify my work and maybe aid me in completing part d I would be grateful. Thank you!Baby walkers are seats hanging from frames that allow babies to sit upright withtheir legs dangling and feet touching the floor. Walkers have wheels on their legsthat allow the infant to propel the walker around the house long before he or she canwalk or even crawl. Typically, babies use walkers between the ages of 4 months and11 months.Because more walkers have tray table in front that block babies’ view of their feet,child psychologists have begun to questions whether walkers affect infants’cognitive development. One study compared mental skills of a random a=sample fothose who used walkers with a random sample of those who never used walkers.Mental skill scores averaged 113 for 54 babies who used walkers (standard deviationof 12) and 123 for 55 babies who did not use walkers (standard deviation of 15). (A) Is there evidence that the mean mental skill score of babis who use walkers is different from the mean mental skill score of babies who do not use walkers? Explain your Answer.Your Turn: The Gas Guzzler Tax is imposed on manufacturers on the sale of new-model cars (not minivans, sport utility vehicles, or pickup trucks) whose fuel economy fails to meet certain statutory regulations, to discourage the production of fuel-inefficient vehicles.

- Part c? I'm stuck, I'm just trying to learn problems like these to help me studyThis 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 =Can someone please help me with this? its all one question or task
- How do I solve the following problem?You want to determine how many loaves of Bread are sold per day at Schat’s Bakery. You stand outside for ten different randomly selected days, count the number of loaves, and then average them. You come up with 421 loaves per day. In reality, Schat’s keeps records of how many loaves they sell per day, and in they averaged 395 loaves per day. What is the static in the above example?(#2) can someone help, i’m super confused
