### Textbook Page Count and Cost AnalysisStatistics students at Oxnard College sampled ten textbooks from the Condor bookstore and recorded the number of pages in each textbook along with its cost. The bivariate data collected is presented in the table below:| **Number of Pages (x)** | **Cost (y)** || ----------------------- | ------------- || 961 | 75.66 || 394 | 41.64 || 282 | 20.92 || 848 | 52.88 || 743 | 49.58 || 443 | 36.58 || 538 | 36.28 || 297 | 35.82 || 929 | 56.74 || 254 | 25.24 |**Exercise for Students:**A student calculates a linear model based on the data. Fill in the blanks to complete the linear equation model:\[ y = \boxed{\phantom{xx}} x + \boxed{\phantom{xx}} \](Please show your answers to two decimal places.)Next, use the model to estimate the cost of a textbook with 613 pages.\[ \text{Cost} = \$\boxed{\phantom{xx}} \](Please show your answer to two decimal places.) #### Understanding the Linear Model- **Independent Variable (x):** The number of pages in the textbook.- **Dependent Variable (y):** The cost of the textbook in dollars. Students are encouraged to calculate the coefficients for the linear equation using regression analysis techniques. After determining the linear equation, they will use the model to predict the cost for a textbook containing 613 pages.This exercise aims to enhance students' understanding of data analysis and the application of linear regression in real-world scenarios.

Enrique wishes to determine if there is a linear correlation between the age of a driver and the death rate for car crashes. The following table represents the age of a driver and the death rate of drivers for car crashes in the same age category per 100 Million Miles Driven. Use a significance level of a = 0.05. Do not round between calculation steps; only round final answers. Driver's Age (x) 17 21 30 32 35 36 47 63 74 Death Rate (y) 5.6 6.6 5.9 5.1 5 5.6 4.9 4.1 3.7 10 10 20 30 40 60 70 90 100 50 Driver Age 80 Death Rate

The table below shows the number of state-registered automatic weapons and the murder rate for several states in the U.S. 11.6 8.4 6.7 3.5 2.7 2.7 2.2 0.9 14.1 11.3 9.9 6.8 6.2 6.3 5.8 I = thousands of automatic weapons y = murders per 100,000 residents Keep in mind, the data in the table do not necessarily imply a direct causal link between the two variables. (In fact, can you think of any reasons why these variables may not be directly related to each other?) Also, the purpose of this question is not to make a political statement about guns or gun control. It's only to illustrate that data such as these sometimes have mathematical relationships that can be modeled with linear equations. Those relationships should always be questioned and examined carefully. With that said, these data can be modeled by the equation y = 0.87z + 3.95. Use this equation to answer the following; A) If this model is oconsistent, how many murders per 100,000 residents can be expected in a state with 8.7…
