i) Explain how you would test for the restrictions on the parameters of the first version of the model, using the first and the second versions of the model regression results. Stating the and alternative hypotheses of your test, carry out an appropriate test to identify the preferred model. Explain what is meant by dummy variables and how you would use a dummy variable […]

1. Verify the formula for triple integrals in spherical coordinates using a change of variables. 2. Suppose that F(x,y) is a conservative vector _eld with potential function f(x,y). Suppose that every vector in F is horizontal (ie: has y component 0). What can you deduce about f? I need all the steps plz.

Please refer to the Project video for complete context about the “Advance Statistics” problem. The objective of the project is to use the dataset ‘Factor-Hair-Revised.csv’ to build an optimum regression model to predict satisfaction. You are expected to Perform exploratory data analysis on the dataset. Showcase some charts, graphs. Check for outliers and missing values (8 marks) Is there evidence of multicollinearity ? Showcase your analysis(6 […]

(a) Use the Recurrent relation for generating the Chebyshev polynomials which is given by To(x) = 1, T1(x) = x, Tn+1(x) = 2xTn(x) Tn-1(x) to approximate the function with a Maclaurins polynomial of order 5. Hence use the Chebyshev polynomials and method of economization to obtain a lesser degree polynomial of approximation, of order 3. (b) Determine the upper error bound, due to the economization. […]

A group conducted a poll of 2059 likely voters just prior to an election. The results of the survey indicated that candidate. A would receive 48_% of the popular vote and candidate B would receive 45_% of the popular vote. The margin of error was reported to be 55_%. The group reported that the race was too close to call. Use the concept of a […]

A man drove 13 mi directly east from his home, made a left turn at an intersection, and then traveled 3 mi north to his place of work. If a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?
Find the equation of the line using the point-slope formula. Passes through the point (_9, 8) and is parallel to the graph y = 8/9x + 4.
