On the data set predict y values to create a residual plot. Certainly! Here is the transcription for the educational website:---**Data Table: Observed and Predicted Values**This table presents a set of observed (`x`, `y`) values alongside their corresponding predicted `y` values. This can be used to analyze the accuracy of a predictive model.| x | y | Predicted y ||----|----|-------------|| 5 | 9 | 6.68 || 9 | 13 | 7.64 || 8 | 2 | 7.40 || 11 | 11 | 8.12 || 12 | 1 | 8.36 || 18 | 12 | 9.80 |**Explanation:**- **x, y Columns:** Represent the observed data points.- **Predicted y Column:** Shows the predicted values calculated from a specific model or algorithm for each corresponding `x` value.This table is useful for comparing observed values against predictions to assess the model's performance. Differences between `y` and `Predicted y` can highlight areas where the model performs well or requires improvement.

The data set of independent variable x, dependent variable y and the predicted y values are given.

A researcher knows that people with higher annual salaries commit fewer crimes. He is creating a regression model to predict the number of crimes a person will commit based on their salary Based on this information alone which of the following MUST be the slope of the regression line choose one 1.00 or 0.50 or -0.50
A linear regression model is designed to predict service charges by a bank (in dollars per month) based on sales revenues of 26 companies who use the services (in millions of dollars). Partial output from Excel gives ŷ = -5428 + 32.756x,, with SSE = 117600, and the p-value = 0.04022 for the estimated slope. Interpret the standard error of the estimate. A B E Approximately 95% of the observed service charges fall within $117600 of the least squares line None of the suggested answers are correct For every $1 million increase in sales revenue, we expect a service charge to increase by $117600 Approximately 96% of the observed service charges fall within $140 of the least squares line. Approximately 95% of the observed service charges equal their corresponding predicted values

Use the estimate yest=3.3x2 - 9.4x - 0.1 to calculate a set of residuals, using a formula or a calculator. Explain your steps, then create a residual plot using this new model and assess its validity
Explain what a residual is and how this relates to the best-fit regression model.
Develop a scatterplot and explore the correlation between customer age and net sales by each type of customer (regular/promotion). Use the horizontal axis for the customer age to graph. Find the linear regression line that models the data by each type of customer. Round the rate of changes (slopes) to two decimal places and interpret them in terms of the relation between the change in age and the change in net sales. What can you conclude? Hint: Rate of Change = Vertical Change / Horizontal Change = Change in y / Change in x
If the relation between Y and X is nonlinear, explain using appropriate mathematical statistics the effect on Y of a change in X.
Data was collected for a regression analysis comparing car weight and fuel consumption. b0 was found to be 32.7, b1 was found to be -7.6, and R2 was found to be 0.86. Interpret the y-intercept of the line. On average, each one unit increase in the weight of a car decreases its ful consumption by 7.6 units. On average, when x=0, a car gets -7.6 miles per gallon. On average, when x=0, a car gets 32.7 miles per gallon. On average, each one unit increase in the weight of a car increases its fuel comsumption by 32.7 units. We should not interpret the y-intercept in this problem.
