For the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year spam.The following ordered pairs shows dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span, (number of units sold, profit) for specific recorded years: (46,600),(48,550),(50,505),(52,540),(54,495). Use linear regression to determine a function Pwhere the profit in thousands of dollars depends onthe number of units sold in hundreds.

An electronics retailer used regression to find a simple model to predict sales growth in the first quarter of the new year (January through March). The model is good for 90 days, where x is the day. The model can be written as follows: ŷ = 103.38 + 2.45x where ŷ is in thousands of dollars. What would you predict the sales to be on day 90? (Enter an exact number as an integer, fraction, or decimal.) thousand dollars
A research company summarized the average time spent every day by teenagers watching cable television beginning in the 2004. state the quadratic regression that respects the data above. Round all values to the nearest hundrenth? determine in which I year then average time spent everyday by teenagers watching cable television is 104 minutes.
A biologist wants to predict the height of male giraffes in feet y, given their age x1, in years, and weight, x2 in pounds. She obtains the multiple regression equation yˆ=14.56+0.00895x1+0.000426x2. Predict the height of a 12-year-old giraffe that weighs 3,100 pounds, rounding to the nearest foot. Provide your answer below: $$ feet
A physics student wants to measure the stiffness of a spring (force required per cm stretched). He knows that according to Hooke's law, there is a linear relationship between the distance a spring is stretched and the force needed to stretch the spring. He collects some data by measuring the force applied to the spring when he stretches the spring by some amount. The plot and the least squares fit is given below.From the regression model, the intercept was found to be -2.532 and the slope was found to be 25.321.Part i).The stiffness of the spring was predicted to beA. -9.961B. 25.321C. 50.642D. -2.532E. 125.84Part ii).Refer to the previous question, the physics student used the regression model to predict that a force of 377.28N would be required to stretch the spring by 15cm. Remarkably, his prediction was horribly wrong. Can you explain why? (Check all that apply)A. He made a prediction outside of the range of forces observed.B. He had outliers or influential points in his data.C.…
On the first day of class, an economics professor administers a test to gauge the math preparedness of her students. She believes that the performance on this math test and the number of hours studied per week on the course are the primary factors that predict a student’s score on the final exam. She estimates the regression model to predict the final exam score using the math test score and number of hours studied per week. A portion of the regression results is shown in the following table. Coefficients Intercept 44.8 Math 0.30 Hours 3.75 (a) Suppose Bella and Ingrid have the same scores on the math test, but Bella studies 2 hours more per week than Ingrid. What is the difference in the final exam scores between the two students? (b) Compute the residual for a student whose math score of 65, studies 5 hours per week, and had a final exam score of 74.
Company X tried selling widgets at various prices to see how much profit they would make. The following table shows the widget selling price, x, and the total profit earned at that price, y. Write a quadratic regression equation for this set of data, rounding all coefficients to the nearest tenth. Using this equation, find the profit, to the nearest dollar, for selling price of 27.5 dollars.
