**Altitude and Temperature Correlation Analysis**Listed below are altitudes (thousands of feet) and outside air temperatures (°F) recorded during a flight. There is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. For the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet).| Altitude (thousands of feet) | 4 | 10 | 14 | 19 | 29 | 31 | 33 ||------------------------------|----|----|----|----|----|----|----|| Temperature (°F) | 55 | 31 | 27 | -1 | -27 | -41 | -54 |### Questionsa. **Find the explained variation.** - [Input field for explained variation] - (Round to two decimal places as needed.)b. **Find the unexplained variation.** - [Input field for unexplained variation] - (Round to five decimal places as needed.)c. **Find the indicated prediction interval.** - [Input field for prediction interval] - (Round to four decimal places as needed.) \[ ^\circ F < y < ^\circ F \]### Instructions1. Enter the explained variation (a) in the respective input field, ensuring values are rounded to two decimal places.2. Enter the unexplained variation (b) in the respective input field, ensuring values are rounded to five decimal places.3. For the prediction interval (c), input the lower and upper bounds of the temperature prediction interval, rounding to four decimal places.### Explanation of Graphs and Diagrams- **Temperature vs. Altitude Table**: The table provides temperature values at various altitudes during the flight. The first row lists altitudes in thousands of feet, and the second row lists corresponding temperatures in degrees Fahrenheit.These data are used to analyze and validate a linear correlation between altitude and temperature. The goal is to determine how temperature changes with altitude and use this relationship for prediction within a 95% confidence interval at a specified altitude.**Note:** It is important to perform the calculations step-by-step, based on statistical methods such as regression analysis, to accurately determine the explained variation, unexplained variation, and prediction interval.

A football coach is looking for a way to identify players that are "under weight". The coach decides to get data for each player's height (x, in inches) and weight (y, in pounds), then does a linear regression. The results are: y = - 52 + 3x,r = 0.9 and the standard error is Se = 10.4. Since there is a strong linear correlation the coach, who also majored in Statistics, decides to identify all "outliers" in the data. Obviously, any player whose weight is above the regression line is not "under weight". So the only outliers the coach is interested in are those that are below the regression line. What is the lowest weight possible for a 69 inch player to not be considered "under weight"? Do not round. Submit Question MacBook Air O00 O00 F4 II F8 F2 F3 F5 F6 F7 F9 23 %24 & 8. E R T. Y F G K.
