(a)
Answer to Problem 38E
From the equation, it is noticed that the
Explanation of Solution
Given:
From the equation, it is noticed that the scatter plot of log (volume) and log (pressure) is linear and the residual figure represents no obvious leftover patterns.

(c)
Answer to Problem 38E
1.28914 atm
Explanation of Solution
Given:
Calculation:
From the part (b)
Putting the value of volume by 17 and calculate
Taking the exponential with 10
Therefore the expected pressure is 1.28914 atm.
