Fit by least square the following data set x| 0.0| 1.0|2.0| 3.0| yl -1.9|1.0| 4.1|4.3| with the model: y = ao + a1 sin(x) + a2 cos(x) Use at least 5 digits in your answers Provide in the box below the answer for the parameter ao Answer: Model parameter a1 (use at least 5 digits) Answer:

What is the model if we use Floor Area and Offices as predictors?   Predict Assessed Value ($’000) Suppose the final model is: Assessed Value ($'000) = 145.921 + 0.307 * Floor Area What would be the assessed value of a medical office building with a floor area of 3500 sqft, two offices, and built 15 years ago? Is this assessed value consistent with actual values in the database?

At the Thanksgiving break, I measured the correlation between the pre-class quiz grade and the average grade in the class for all 33 students in my stats classes. Below is the output from those results.   Correlation Pearson correlation of PreClass and Grade = 0.705630 P-Value = < 0.0001   Regression Equation Grade = 0.24333 + 0.006369P reClass (a) Determine the critical value in the table and explain how you know these two variables would be considered correlated. (b) Knowing that there is correlation, use this model to predict the average grade of a student in this class who did not complete any pre-class quizzes. (c) Assuming everyone in this class completed at least one quiz, would you describe the previous problem as interpolation or extrapolation?
