Answer to Problem 67SR
Explanation of Solution
Given:The data of Barometric pressure at various height as shown in below table.
The given table show barometric pressure at different height.
In part (a) plot scatter diagram and line of best fit.
The equation of line of best fit,
If the height is 60,000 feet.
Put
So,
The value of pressure is negative. Negative value of pressure is not valid because minimum value of pressure is 0 in vacuum.
So, the pressure is not reasonable.
(c)
To explain:About line of best fit.
(c)

Explanation of Solution
Given: The data of Barometric pressure at various height as shown in below table.
The given table show barometric pressure at different height.
In part (a) plot scatter diagram and line of best fit.
The equation of line of best fit,
If the height is 60,000 feet.
Put
The line of best fit is best model because this does not show pressure at very high.
