A student calculates a linear model

yy = xx + . (Please show your answers to two decimal places)**Use the model above** to estimate the cost when number of pages is 629

Cost = $ (Please show your answer to 2 decimal places.)

Step 1

**Regression:**

The regression analysis is conducted here by using EXCEL. The software procedure is given below:

- Enter the data.
- Select
**Data > Data Analysis > Regression> OK**. - Enter
**Input Y Range**as**Cost**. - Enter
**Input X Range**as**Number of pages**. - Click
**OK**.

Step 2

The output using EXCEL is as follows:
