Statistics students in Oxnard College sampled 9 textbooks in the Condor bookstore and recorded the number of pages in each textbook and its cost. The bivariate data are shown below:Number of Pages ( x )Cost( y )32241.2895103.523222.261874.839451.481489.488497.491989.9929109.9A student calculates a linear modely = x + . (Please show your answers to at least 4 decimal places)Use the model to estimate the cost when number of pages is 407.Cost = $ (Please show your answer to 2 decimal places.)

Respuesta :

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

table:

number of pages (x) and cost (y)

Step 02:

linear model:

graph method:

linear model equation:

y = 0.1057x + 4.9564

cost, x = 407 pages:

y = 0.1057(407) + 4.9564 = 47.98

cost = $47.98

That is the full solution.
